Ch. 4 · Pre-Drive Conduct

On a road with a height restriction sign, if the vehicle body itself is below the height shown on the sign, you may pass even if the total height including loaded cargo exceeds the height shown on the sign.

[True / False · Medium]

Answer: ✕ False

Explanation

A height restriction sign prohibits the passage of vehicles whose total height, including cargo loaded on the vehicle, exceeds the value shown on the sign. You may not pass unless the height including cargo—not just the vehicle body—is below the restriction. Chapter 4, Section 4 of the Rules of the Road (Riding and Loading) states that it prohibits the passage of vehicles higher than the height shown on the sign (including the height of loaded cargo).

As long as the car itself fits under the sign, I can go through, right?

Misaki
No, that's false. The restriction applies to your total height—vehicle plus cargo. If your load sticks up and you exceed the limit, you can't pass.

Oh, so even if my truck is short enough, a tall load blocks me?

Exactly. Always measure from the ground to the very top of whatever you're carrying.
