Get clear, practical answers to the most common questions about the M4g - Lorries road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the French driving theory exam in France.
The M4g plate means that the primary traffic sign it accompanies is specifically directed at lorries. If you are driving a different type of vehicle, such as a car, the main sign's instruction might not apply to you. Always check if your vehicle type is indicated.
Generally, no. The M4g plate indicates that the rule shown by the main sign is intended only for lorries. If you are driving a passenger car (category B) or a vehicle not classified as a lorry, you are usually exempt from the restriction or obligation shown.
In France, 'lorry' typically refers to vehicles designed for transporting goods with a maximum authorized mass exceeding 3.5 tonnes (M.M.A. or P.T.A.C.). If you are driving a smaller commercial vehicle or a van, it may not be covered by the M4g restriction. Consult your vehicle's registration documents if you are uncertain.
A common trap is assuming that any sign with a supplementary plate applies to all vehicles. With the M4g plate, learners might incorrectly apply a prohibition or obligation intended only for lorries to their own car. Always focus on whether your vehicle category is explicitly mentioned or excluded.
Yes, the M4g plate is always used in conjunction with another main traffic sign. It modifies the application of that sign. For example, a prohibition sign with an M4g plate below it would mean that only lorries are prohibited from entering or performing a certain action.
