When transporting explosives, you may not park within how many feet of a tunnel?

When transporting explosives, it is essential to maintain a safe distance from potential hazards, such as tunnels, to minimize the risk of accidents and facilitate effective emergency response. The regulation stipulates that you may not park within 300 feet of a tunnel when transporting explosives. This distance ensures that if an incident were to occur, the explosive materials would not pose a significant threat to the structure of the tunnel or to individuals and vehicles within that area.

The need for such a regulation arises from the potential consequences of an explosion in a confined space like a tunnel, where the effects can be exacerbated, leading to severe damage and hazards to public safety. The specified distance acts as a precautionary measure to create a buffer zone that protects both the transport vehicle and the surrounding environment.
