Speed limits for solid tire and explosive vehicles
Read the official text at honolulu.gov ↗This section sets special speed rules for two types of vehicles. Vehicles with solid rubber tires cannot go faster than 10 miles per hour on any highway. Vehicles carrying explosives must follow the speed on their permit or the road's speed limit, and can only use freeways if they can keep up with the minimum speed.
