重量制限フランス

It prohibits vehicles or vehicle combinations whose relevant mass exceeds the value displayed on the sign.

It is commonly a circular regulatory sign showing a mass in tonnes, kilograms or another local unit.

It is normally a prohibition. A vehicle exceeding the displayed limit may not continue beyond the sign.

Actual loaded mass is the weight of the vehicle as it is currently travelling, including the vehicle itself, its load, driver, passengers and other relevant equipment.

Maximum authorised mass is the highest total mass at which the vehicle is legally approved to operate. It is normally recorded in the vehicle documents.

No. A lightly loaded vehicle may have an actual mass below its maximum authorised mass. A restriction may legally refer to either measurement, depending on the sign and local law.

Yes. Cargo, passengers, fuel, equipment and other carried items may all contribute to the vehicle’s actual loaded mass.

Where the restriction concerns actual loaded mass, the driver and other occupants are normally included.

This depends on the wording of the restriction. It may apply to each vehicle separately or to the combined mass of the complete vehicle combination.

An axle-weight limit restricts the amount of mass carried by one axle or axle group rather than the total mass of the vehicle.

A vehicle may comply with the total weight limit while too much of its load is concentrated over one axle, creating excessive stress on the road or bridge.

They are often used at bridges, weak roads, historic centres, tunnels, temporary structures and roads unsuitable for heavy traffic.

Not necessarily. The displayed legal limit may include engineering and safety margins and should not be interpreted as the structure’s exact failure point.

A sign normally prohibits vehicles exceeding the displayed value. The driver must still be certain that the relevant mass does not exceed it.

The most reliable method is to use an authorised or suitable weighbridge. Vehicle documents alone normally show approved limits rather than the vehicle’s current loaded mass.

An estimate may help with planning, but it must include the vehicle, fuel, occupants, equipment, load and trailer. A weighbridge is preferable when the remaining margin is small.

No. Moving cargo within the vehicle does not change its total mass, but it can change the load carried by each axle.

Yes, when done lawfully and safely. The vehicle may continue only after its relevant mass complies and the remaining load is properly secured.

Yes. Temporary restrictions may protect a damaged bridge, weakened road, roadworks structure or road affected by flooding or thawing.

Yes. Lane-specific signs may direct heavier vehicles towards a lane or structure designed to carry them.

Yes. Advance signs may give the distance to the restriction or indicate a diversion so affected vehicles can choose another route.

No. The applicable general, zonal or posted speed limit remains in force.

No. Traffic lights, priority signs and ordinary priority rules remain applicable.

Do not continue. Stop where safe and follow a signed diversion or another route suitable for the vehicle’s mass.

No. Navigation information may be incomplete or outdated. Traffic signs and official restrictions always take precedence.

Only when reversing is lawful and can be completed safely. Use assistance where necessary, particularly with a long or heavy vehicle combination.

The vehicle may damage the road or structure and may be stopped, fined, unloaded or prohibited from continuing under local law.
