What does a "No vehicles over width shown" traffic sign restrict?

A "No vehicles over width shown" traffic sign specifically restricts vehicles from exceeding a specified width. This means that any vehicle that measures wider than the designated width is prohibited from passing through that area. The primary purpose of this sign is to ensure safety by preventing larger vehicles, which may not fit in certain roadways, bridges, or tunnels, from entering areas where they could cause accidents, block traffic, or cause damage to infrastructure.

The focus on restricting vehicles over the stated width is critical in maintaining clear and safe pathways for all road users. Proper compliance with this sign helps in preventing incidents that could arise from exceeding width restrictions, such as collisions with roadside structures or becoming lodged in narrow passageways.
