Signs for low bridges and height limits
Height-limit signs also matter to category B drivers when you drive with roof cargo, a box or a tall vehicle.
Signs for low bridges and height limits often seem relevant only to trucks. But category B drivers also need to understand them, especially when using a roof box, van, bicycle rack or an unfamiliar vehicle height.
What you need to know
- A height limit applies to the vehicle’s actual height, not only to standard passenger-car height.
- A roof box, skis and cargo can make the car taller than you are used to.
- Reading the signs early gives you time to choose another route safely.
Typical situations
| Situation | What you should do | Common mistake |
|---|---|---|
| Roof box on a family trip | Know the total height before entering a parking garage or tunnel. | Guessing that the car will “probably fit”. |
| Rented van | Check the stated height before driving in the city centre or indoors. | Relying on your normal experience from your own car. |
| Signed low bridge on an unfamiliar road | Reduce speed and prepare an alternative route. | Continuing forward just to see whether it might work. |
Common mistakes
- Forgetting the extra height from equipment on the roof.
- Reading the sign too late to choose a safe solution.
- Thinking that a few centimetres of “clearance” are always enough.
