Mexico
1. Mexico
Mexico stretches from the southern border of the United States to Guatemala and Belize, with coastlines on the Pacific Ocean, Gulf of Mexico and Caribbean Sea. Traffic drives on the right. Its road network ranges from busy metropolitan streets to long desert highways and winding mountain routes. A particularly Mexican distinction is the choice on many intercity journeys between carreteras libres, which are free to use, and higher-standard autopistas de cuota, where tolls are collected.
Mexico has no nationwide vignette. Toll-road payment depends on the operator; CAPUFE uses toll plazas and the IAVE electronic-tag system, while cash remains in use during the transition toward greater electronic collection. Traffic regulation combines federal, state and municipal rules, although national law establishes minimum road-safety requirements and maximum speed ceilings. Road signage is standardised nationally and written signs are primarily in Spanish, together with widely recognisable traffic symbols.
AI
Which side of the road do you drive on in Mexico?
Drive on the right-hand side of the road.
Which side should you overtake on in Mexico?
Normally overtake on the left. On federal roads, passing on the right is permitted only in specified situations, such as when the vehicle ahead is turning left or where there are two or more lanes travelling in the same direction.
What is the emergency telephone number in Mexico?
Call 911 for general emergency assistance. On roads operated by CAPUFE, 074 provides free 24-hour roadside assistance, medical assistance and road information.
Are traffic rules the same throughout Mexico?
Not completely. Federal law establishes nationwide minimum road-safety measures, while states and municipalities also issue and enforce their own traffic regulations. Local rules for matters such as parking, turning and vehicle restrictions can therefore differ.
What is the alcohol limit for drivers in Mexico?
Mexico's national mobility law prohibits driving above 0.05% BAC (0.05 g/dL) or 0.25 mg/L of alcohol in breath. State and local rules may impose stricter requirements.
What is the alcohol limit for motorcycle riders in Mexico?
Motorcycle riders are subject to a lower national ceiling of 0.02% BAC (0.02 g/dL) or 0.1 mg/L in breath.
What is the alcohol limit for passenger and goods transport drivers in Mexico?
Drivers of vehicles used for passenger or goods transport must have no alcohol concentration in their breath or blood under the national mobility law.
What are the general speed limits in Mexican cities?
Mexico's national law sets maximum ceilings rather than one universal urban speed limit: 30 km/h on secondary and tertiary streets, 50 km/h on primary avenues without controlled access and 80 km/h on the central lanes of controlled-access avenues. Lower posted or local limits can apply.
What are the speed limits around schools and hospitals in Mexico?
The national maximum is 20 km/h around hospitals and similar care facilities. School areas are limited to 20 km/h on secondary and tertiary streets and up to 30 km/h on primary roads and highways.
What is the maximum speed on state roads in Mexico?
The national ceiling is generally 80 km/h outside urban areas and 50 km/h within urban areas on state roads. Posted lower limits must be followed.
What is the maximum speed on federal roads and motorways in Mexico?
National law sets maximum ceilings of 110 km/h for cars, 95 km/h for buses and 80 km/h for goods vehicles on federal roads and autopistas. The signed limit may be lower.
Do you need a vignette to drive in Mexico?
No. Mexico has no nationwide vignette. Charges apply when using particular toll roads, bridges and other toll facilities.
How are toll roads paid for in Mexico?
Toll roads commonly use toll plazas. CAPUFE supports the IAVE electronic tag on compatible roads and bridges, while cash is still used at toll plazas as the network transitions toward wider electronic toll collection. Payment methods can differ between operators.
Are seat belts compulsory in Mexico?
Yes. Mexico's national mobility law requires seat-belt use by all passengers in motor vehicles, subject to the applicable technical requirements.
Are child car seats compulsory in Mexico?
National law requires a person under 12 years old, or someone whose physical size requires it, to travel in a rear seat using an appropriate child-restraint system or safety seat that meets the applicable Mexican standard.
Are motorcycle helmets compulsory in Mexico?
Yes. An appropriate helmet is compulsory for both motorcycle riders and passengers under the national mobility law.
Must motorcycles use their headlights during the daytime in Mexico?
On federal roads, motorcycles must travel with their lights switched on at all times, including during daylight.
Is motorcycle lane splitting allowed in Mexico?
On federal roads, motorcycles may not travel between traffic lanes or between adjacent rows of vehicles. Local motorcycle rules on streets under state or municipal jurisdiction should also be checked.
Can you use a mobile phone while driving in Mexico?
National law prohibits talking on or otherwise using a mobile phone or electronic communication device while driving, including reading or sending messages, unless it is used through hands-free technology.
Who has priority at an uncontrolled intersection in Mexico?
On federal roads, a vehicle already in the intersection has priority. If vehicles arrive simultaneously from different roads, they must stop and the vehicle approaching from the right proceeds first, subject to exceptions such as differences in road priority.
Who has priority at roundabouts in Mexico?
On federal roads, traffic circulates anticlockwise and vehicles already within the roundabout have priority. On local streets, also follow the applicable signs, signals and state or municipal rules.
Must drivers give way to pedestrians at crossings in Mexico?
Yes. Pedestrian priority is included among Mexico's national minimum traffic measures. On federal roads without traffic signals or officers, drivers must give way to pedestrians already using a marked crossing.
What should you do when an emergency vehicle approaches in Mexico?
On federal roads, give way to emergency vehicles using their warning signals. Move as close as safely possible to the right side of the road and stop if necessary until the emergency vehicle has passed.
Can you turn right at a red light in Mexico?
There is no single nationwide rule that should be assumed everywhere. Turning rules are also governed by state and municipal traffic regulations, so obey the traffic signal, signs and rules applying where you are driving.
Is motor vehicle insurance compulsory in Mexico?
Vehicles travelling on federal roads and bridges must have third-party liability insurance covering damage that may be caused to other people or their property. States may impose additional insurance requirements.
Can tourists drive in Mexico with a foreign driving licence?
Requirements can depend on the circumstances and jurisdiction. Federal-road rules expressly recognise a foreign driver's licence issued by the competent authority of their place of residence when driving a legally admitted foreign-plated vehicle. Visitors should also check state requirements and rental-company conditions.
Are there vehicle restrictions in Mexico City?
Yes. The Hoy No Circula programme restricts certain vehicles from circulating in Mexico City and the surrounding metropolitan area according to factors such as registration plates and emissions classification. Restrictions can become stricter during an environmental contingency, and vehicles from outside the area can also be affected.
Can foreign tourists obtain an exemption from Hoy No Circula?
Eligible visitors with qualifying vehicles registered outside the metropolitan area can apply for the free Pase Turístico, which can exempt the vehicle from normal Hoy No Circula restrictions for a limited period. The pass does not override restrictions imposed during an environmental contingency.
What should you do if your vehicle breaks down on a Mexican toll road?
Move out of the traffic lane where it is safe to do so and warn other road users appropriately. On roads operated by CAPUFE, call 074 for free roadside, mechanical or medical assistance and current road information.
What languages are used on road signs in Mexico?
Mexico uses nationally standardised traffic signs with internationally recognisable symbols, while written road information is primarily in Spanish.
