76. Parallel parking

Parallel parking is a method of parking a vehicle parallel to the edge of the road, usually in a space between two parked vehicles. It is commonly used where parking spaces are arranged along the side of a street.

Parallel parking normally involves positioning the vehicle beside the available space and reversing into it while carefully checking mirrors, blind spots and surrounding traffic. The vehicle should finish within the permitted parking area and close enough to the road edge without obstructing other road users.

How should a vehicle be positioned after parallel parking?

The vehicle should be completely within the permitted parking area, reasonably close to the road edge and positioned so that it does not unnecessarily obstruct traffic or access to other vehicles.

77. Alternate-side parking

Alternate-side parking is a parking system in which vehicles must park on different sides of a street at different times or on different dates. The system may be used to keep streets accessible, distribute parking or allow activities such as street cleaning or maintenance.

The applicable side may change daily, weekly, monthly or according to another schedule. Drivers must check the local signs and rules carefully, because the timing and method of changing sides differ between countries and municipalities.

Which side of the street is permitted in French half-monthly alternate-side parking?

Where the municipality has adopted this system, parking is on the side with odd-numbered buildings from the 1st to the 15th and on the even-numbered side from the 16th through the final day of the month. It is not automatic in every French street.

🔗 legifrance.gouv.fr • France, Road Code, Article R417-2, alternate-side parking

At what time do drivers change sides in France?

Unless the competent authority specifies otherwise, the changeover is made on the final day of the half-month period between 20:30 and 21:00. Follow any local order and signs.

🔗 legifrance.gouv.fr • France, Road Code, Article R417-2, alternate-side parking

78. Parking meter

A parking meter is a device used to regulate and usually collect payment for parking in a designated parking space or area. It may require drivers to pay for a particular parking period, enter a vehicle registration number or obtain a ticket that must be displayed in the vehicle.

Parking meters may accept coins, payment cards, contactless payments or electronic payment methods, depending on the local system. Drivers must follow the instructions, operating hours, maximum parking duration and tariffs indicated on the meter, nearby signs or other official parking information.

Do parking-meter payments in Paris require a ticket behind the windscreen?

No. Paris uses a number-plate-based digital payment record; entering the correct registration number is essential. Paying at a machine or with the authorised app does not normally require displaying a paper ticket.

🔗 paris.fr • City of Paris, parking meter, digital plate registration and defective machine

Is parking free in Paris if the nearest meter is broken?

No. Paris instructs drivers to use another working meter for the same type of parking area or an authorised payment app. A defective machine does not cancel the payment requirement.

79. Parking disc

A parking disc is a device used to indicate the time a vehicle was parked in an area where parking duration is limited. The driver sets the disc to the required arrival time and displays it clearly inside the vehicle.

Parking-disc systems are commonly used in blue zones or other time-limited parking areas. The permitted parking duration, operating hours and method for setting the disc depend on national or local rules and the traffic signs in place.

Does France use one nationwide time limit for every parking-disc zone?

No. The municipality specifies the parking duration and period, indicated by signs or a supplementary panel. The disc must follow the French approved model and be visible at the front of the parked vehicle.

🔗 legifrance.gouv.fr • France, Road Code, Article R417-3, parking-duration disc

80. Disabled parking

Disabled parking refers to parking spaces and parking privileges reserved for people with disabilities who meet the applicable eligibility requirements. Reserved spaces are normally identified by the international wheelchair symbol and are positioned to provide easier access to nearby facilities.

Use of a disabled parking space generally requires a valid disabled parking permit or card. The permit normally belongs to the eligible person rather than to a particular vehicle and may only be used when that person is driving or travelling in the vehicle.

How does free accessible street parking work in Paris?

Vehicles transporting someone with a valid CMI-S disability parking card or European disability parking card may use eligible paid on-street spaces without a parking charge. In Paris, a free Ticket HANDI or recognised Handi'Stat registration is normally needed to activate the exemption for paid spaces. Different municipalities may use different procedures.

🔗 paris.fr • City of Paris, free street parking for disability parking-card holders and Ticket HANDI

Does a disabled parking card remove every time or display requirement in Paris?

No. A Ticket HANDI is valid for 24 consecutive hours and a new ticket is needed after that; a vehicle registered in Handi’Stat may stay up to seven consecutive days. Reserved accessible bays also have a seven-day limit. Display the original valid card in reserved bays and when using a Ticket HANDI; it need not be displayed in a paid bay for a registered Handi’Stat vehicle.

🔗 paris.fr • City of Paris, parking for people with disabilities

Can a French municipality impose a time limit on CMI parking concessions?

Yes, but not below 12 hours. This concerns the CMI parking concession. Car parks with entry and exit equipment operable from the vehicle may still charge.

81. Traffic management

Traffic management is the organised control, regulation and guidance of road users to improve safety, traffic flow and the efficient use of roads. It can include traffic lights, road signs, road markings, lane controls, variable speed limits, diversions and directions given by authorised persons.

Traffic management may be permanent or temporary. Temporary measures are commonly introduced during roadworks, congestion, collisions, public events or other incidents. Drivers and other road users must follow the signs, signals and instructions applying at the location, even when they differ from the normal traffic arrangement.

82. Merging

Merging is the process of joining a stream of traffic from another lane or road, such as when an entry lane joins a motorway or when two traffic lanes become one. The merging driver must observe surrounding traffic, signal when required and enter an appropriate gap safely.

Drivers already in the continuing traffic lane should remain alert to merging vehicles and avoid unnecessarily preventing them from joining. Special zipper-merging rules may apply when traffic is heavily congested and a lane ends.

Who gives way when joining a French autoroute?

The driver on the entry slip road must give way to vehicles already on the autoroute.

🔗 legifrance.gouv.fr • French Road Code — R412-9–10, R414-1–3, R421-3

Must you signal before rejoining French traffic after parking?

Yes. Warn other road users before returning to the traffic stream.

🔗 legifrance.gouv.fr • French Road Code — R412-9–10, R414-1–3, R421-3

83. Reversing

Reversing means driving a vehicle backwards. It is commonly used when parking, leaving a confined space or repositioning a vehicle where forward movement is not practical.

Before reversing, the driver should check mirrors and blind spots, look carefully around the vehicle and make sure the area behind is clear. Reversing should be performed slowly and only for as long as necessary because visibility behind the vehicle is often limited.

Can you reverse on a French autoroute after passing an exit?

No. Reversing on an autoroute is prohibited.

84. U-turn

A U-turn is a driving manoeuvre in which a vehicle turns around to travel in the opposite direction. It normally involves crossing part of the roadway and re-entering traffic facing the direction from which the vehicle came.

Before making a U-turn, the driver should check surrounding traffic, pedestrians and cyclists, signal when required and make sure there is enough visibility and space to complete the manoeuvre safely. U-turns may be prohibited by traffic signs or on particular types of roads.

Can a gap in a French autoroute central reservation be used for a U-turn?

No. The U-turn prohibition also applies at gaps in the central divider.

🔗 legifrance.gouv.fr • France, Code de la route R421-4,R421-6 and R421-7 — motorway entry/exit, no reversing/U-turns and emergency stopping

85. Carpool

Carpool means sharing a car journey with one or more other people who are travelling in the same direction. The occupants may share travel costs or simply travel together to reduce the number of separate vehicles making the same journey.

Carpooling is commonly used for commuting, school journeys and longer-distance travel. Some road networks provide dedicated carpool parking areas where travellers can meet, leave one vehicle and continue their journey together.

Is carpooling the same as carsharing?

No. Carpooling means several people travelling together in the same vehicle, while carsharing means different users having access to the same shared vehicle at different times.

🔗 assets.publishing.service.gov.uk • Department for Transport, car clubs rapid evidence assessment, 2024

86. Traffic jam

A traffic jam is a situation where traffic becomes heavily congested and vehicles move very slowly or stop for extended periods. Traffic jams are commonly caused by high traffic volumes, accidents, roadworks, lane closures or poor weather. Drivers should remain patient, keep a safe distance, avoid unnecessary lane changes and watch for motorcycles, emergency vehicles and sudden braking. Where lanes merge during congestion, local rules may require drivers to use a zipper-merging system.

Can you enter a French junction if a queue will leave you blocking cross traffic?

No. Enter only if you can avoid becoming immobilised and obstructing other roads.

🔗 legifrance.gouv.fr • French Road Code — R412-9–10, R415-2, R421-5

87. Uncontrolled crossroad

An uncontrolled crossroad is an intersection where traffic priority is not specifically regulated by traffic lights, an authorised person or signs assigning priority to particular approaches. Drivers must therefore determine who has priority using the default traffic rules that apply in that country.

The applicable rule varies between countries and may include priority from the right, priority from the left or another default right-of-way rule. Drivers should approach an uncontrolled crossroad carefully, observe traffic from every direction and never assume that a wider or busier road automatically has priority.

Which vehicle has priority at an unsigned crossroad in France?

Under Article R415-5, when drivers approach from different roads and no other priority rule applies, the driver approaching from the left must give way to the driver from the right (priorité à droite).

🔗 legifrance.gouv.fr • French Road Code — R415-5–7, R415-11

Can signs override priorité à droite in France?

Yes. Stop, Give Way, priority-road and other traffic controls can change which approach has priority. The right-hand default applies only where no different provision governs the intersection.

🔗 legifrance.gouv.fr • French Road Code — R415-5–7, R415-11

88. Road surface

A road surface warning indicates that the road ahead may be uneven, damaged or in poor condition and could affect the stability, steering or braking of a vehicle. The hazard may include bumps, depressions, potholes, broken pavement or other irregularities in the road surface.

Drivers should reduce speed where necessary, maintain a safe distance and avoid sudden steering or braking when passing over an irregular surface. The exact meaning and appearance of the warning sign vary between countries, so drivers must follow the local traffic signs and regulations.

Does a road surface warning impose a specific speed limit?

Not normally. A warning sign alerts drivers to a hazard rather than establishing a numerical speed limit. A separate speed-limit sign may be used where a particular maximum speed is required.

89. Ring road

A ring road is a road or connected system of roads that runs around or partly around a city, town or urban area. It is designed to distribute traffic between different parts of the area and to allow through traffic to bypass congested central streets.

A ring road is not necessarily a motorway or expressway. It may consist of motorways, divided highways, ordinary roads or a combination of different road types. The applicable speed limits, access restrictions, priority rules and lane rules therefore depend on the individual section and the local traffic signs and regulations.

90. Exit

An exit is a designated route or point where traffic leaves a road, motorway, expressway or other major route. On high-speed roads, an exit usually leads from the main carriageway onto an exit lane or ramp that connects with another road or destination.

Drivers approaching an exit should follow the direction signs and road markings, move into the appropriate lane in good time and adjust their speed as necessary after leaving the main traffic flow.

91. Information point

An information point is a designated place where travellers can obtain information about the surrounding area, local services, tourist attractions, routes or other useful facilities. It may be located beside a road, at a rest area, in a town or near an important destination.

Information points are often indicated by a service or information sign. Depending on the location, they may provide maps, brochures, route information, tourist assistance or digital information for visitors.

92. Horse riding

Horse riding includes activities involving horses and riders. In road traffic, an equestrian or horse rider may use roads, bridleways or specially designated routes, depending on the rules and infrastructure provided.

Drivers approaching horses and riders should reduce speed, leave sufficient space and avoid sudden noise or movements that could frighten the animal. Riders must also follow the traffic rules that apply to them.

93. Provisional licence

A provisional licence allows a learner driver to practise driving on public roads before obtaining a full driving licence. The conditions vary between countries and may determine whether the learner must be accompanied by an approved supervisor, which vehicles may be driven, where and when driving is permitted and how long the licence remains valid. A provisional licence is normally subject to stricter rules than a full licence and is intended specifically for learning and gaining practical driving experience.

What is a provisional driving licence?

The meaning depends on the jurisdiction. In Great Britain and Flanders, a provisional licence can authorise learning under specified conditions. In the Australian Capital Territory, a provisional licence follows the learner stage and assessment. It is not a universal synonym for a learner licence.

Can you drive alone with a provisional licence?

Check the jurisdiction, licence stage and its conditions. In Flanders, some provisional licences require a registered supervisor, while another option permits independent practice after approved training. In Great Britain, car learners must follow the supervision rules. Other countries may use provisional for a later licensing stage.

🔗 gov.uk • GOV.UK, driving lessons and learning to drive; GB learner rules

How long is a provisional licence valid?

There is no universal validity period or renewal procedure. Check the issuing authority’s rules for the particular licence. For example, Flanders distinguishes 18-month and 36-month provisional learner licences; another jurisdiction may use provisional for a different stage altogether.

94. Hazardous cargo

Hazardous cargo, also called dangerous goods, consists of substances or articles that can create a significant risk to people, property or the environment during transport. Examples include explosives, flammable liquids and gases, toxic substances, corrosive materials and radioactive substances.

Transporting hazardous cargo can require special packaging, labels, vehicle markings, documentation, equipment and driver training. Additional route or tunnel restrictions may also apply depending on the type and quantity of dangerous goods being carried.

Wikimedia.org • Marc Mongenet • CC BY-SA
Can hazardous cargo be prohibited on certain roads or in tunnels?

Yes. Routes and tunnels can restrict vehicles carrying dangerous goods. The signs, applicable dangerous-goods rules and the load determine whether a restriction applies. For example, Great Britain uses ADR tunnel categories A to E; these are not general speed categories for all vehicles.

95. Emergency exit

An emergency exit is a marked escape route that allows road users to leave a tunnel or other enclosed traffic facility during a serious incident such as a fire, smoke development or another emergency. Emergency exits lead towards a safer area separated from the immediate danger.

In an emergency, occupants should leave their vehicle when evacuation is necessary and follow the emergency-exit signs and instructions. They should move away from the danger rather than remaining inside the tunnel or returning to their vehicle.

96. Runaway truck ramp

A runaway truck ramp, also called an emergency escape lane, is a specially constructed lane designed to stop a vehicle that has lost effective braking, particularly a heavy vehicle descending a steep hill. The ramp may use an uphill gradient, deep gravel or another energy-absorbing surface to slow and stop the vehicle.

A driver who has lost braking ability should enter the escape ramp as early and safely as possible rather than trying to continue down the hill. Escape ramps are emergency facilities and must not be used for ordinary stopping, parking or turning.

Can you use a runaway truck ramp for normal stopping or parking?

No. An escape ramp is an emergency safety facility and should be kept clear for vehicles that have lost effective braking or control.

97. Radio service

A radio service is a radio broadcast that provides drivers with traffic information such as congestion, road closures, accidents, weather conditions or other events affecting a journey. Roadside signs may indicate a particular radio station and frequency where traffic information is available.

Drivers can tune to the indicated frequency to receive local traffic information while travelling through the area. The service is informational and does not replace traffic signs, signals or instructions from authorised persons.

Do radio traffic reports override road signs?

No. Radio information can help drivers anticipate conditions and choose a route, but drivers must continue to obey traffic signs, signals, road rules and instructions from authorised persons.

98. Oversize load

An oversize load is a load that causes a vehicle or vehicle combination to exceed the normally permitted dimensions for road traffic, such as maximum length, width or height. Oversize loads often involve large machinery, construction components or other items that cannot reasonably be divided into smaller loads.

Transporting an oversize load may require a special permit, an approved route, warning signs, lights or escort vehicles. Drivers must comply with the conditions imposed by the authorities responsible for the roads on which the transport takes place.

Why might an oversize load need an escort vehicle?

An escort can warn other road users and help an unusually large vehicle negotiate its planned route. The required escorts depend on local rules and the transport’s dimensions and weight. Do not assume a private escort has police powers to stop or direct traffic; British guidance expressly distinguishes those roles.

99. Lane

A lane is a longitudinal part of a roadway intended to accommodate a line of moving vehicles. A roadway may contain one or several lanes for traffic travelling in the same or opposite directions.

Lanes are commonly separated by continuous or broken road markings. Traffic signs, lane arrows and lane-control signals may indicate which vehicles may use a lane, which direction traffic must follow or whether a lane is open or closed.

An tyre inflation station is a facility where drivers can check and adjust the air pressure in their vehicle's tyres. It is commonly located at filling stations, service areas, garages or other roadside facilities and usually provides a pressure gauge and compressed-air hose.

Correct tyre pressure contributes to safe handling, braking, tyre wear and fuel or energy efficiency. Drivers should inflate their tyres to the pressure recommended for their vehicle and load conditions.
