What does the B13 'Weight Limit' road sign mean in France?

If your vehicle exceeds the weight limit indicated by the B13 sign, you must not enter the restricted area. Instead, you should immediately look for and take an alternative, lawful route that allows your vehicle to pass safely. Plan your route in advance to avoid being caught unaware.
