Which vehicles can cause serious accidents when this traffic sign is ignored?

This traffic sign indicates a **height restriction of 3.8 meters**. Vehicles higher than 3.8 meters are not allowed to pass, because they could hit a bridge, tunnel, or other obstacle above the road. If this sign is ignored by a vehicle that exceeds the indicated height, it can lead to serious accidents or damage to both the vehicle and the structure.

In your quiz, vehicles like the one with a height of 4 meters would be too tall and are at risk. That’s why only answer 1 is correct: its height exceeds the limit, which would make it dangerous to ignore the sign. To solve similar questions, always check the **height** and compare it to the restriction shown on this type of sign. Vehicles under the height limit are allowed to pass; those above are not.
