How should you approach an underpass or low clearance area?

When approaching an underpass or low clearance area, it's essential to check if the height is marked. This is important because underpasses can vary in height, and ensuring that your vehicle can safely pass underneath is crucial for preventing accidents or damage to the apparatus. By verifying the height, you can make an informed decision about whether to proceed or take an alternative route, ultimately ensuring the safety of the crew and the integrity of the vehicle.

Relying solely on intuition or reducing speed without checking the height can lead to dangerous situations, as you may misjudge whether the vehicle can fit. Similarly, assumptions about safety can result in serious consequences if the clearance is less than expected. Increasing speed to clear the area quickly can also be hazardous, as it reduces reaction time and may lead to a failure to assess the situation adequately. Therefore, checking for height markings is the most prudent and responsible approach.
