What should the maximum height of a car be, including any load?

The maximum height of a car, including any load, should not exceed 4 meters. This regulation is in place to ensure safety on the road, as it helps avoid collisions with bridges, overhead signs, and other infrastructure. Such regulations are particularly important for managing traffic flow and preventing accidents that could occur from vehicles that are too tall for certain roadways or underpasses.

While the other options provide higher maximum heights, they exceed safety regulations and would not be practical for most road scenarios. It’s important for drivers and vehicle owners to be aware of height limits to ensure compliance and maintain safety standards for everyone on the road.
