What is the maximum depth of water allowed in a clear zone?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (B)

The maximum depth of water allowed in a clear zone is typically set at 2 feet. A clear zone is defined as an area adjacent to a roadway that is free from obstacles and allows for the recovery of errant vehicles. When designing roadways, it is crucial to limit potential hazards that could pose a risk to vehicle occupants. A maximum depth of 2 feet for water in the clear zone is based on safety considerations. Depths beyond this can significantly increase the risk of vehicle loss of control or accidental submersion, compromising the safety of drivers and passengers. The aim is to ensure that this area does not create an additional hazard, while also maintaining a level of safety that allows errant vehicles a chance to recover safely. Shallower clear zones with no more than 2 feet of water provide a better chance for drivers to navigate out of the water if their vehicle inadvertently enters, reducing the likelihood of serious accidents or injuries. Thus, this 2-foot limit is a design standard adopted in many transportation designs to enhance roadway safety.
