If there is a school shooting that wounds one, everyone evaluates it for prevention and response in the future. We usually don't do a good job of this on major transportation emergencies on our highways. We have discussed quick clearance issues already. Liability exemptions or reductions to facilitate quick clearance of load materials and trucks gives responders the authority needed to act decisively. This can be accomplished through policy, but, some agencies want this placed in law.
Additional effort is needed in every state for updating towing regulations.
Although this is primarily a police issue, DOT can play a significant role. Regulations for large tow trucks were developed over 30 years ago. At that time, legal truck weights were much lighter than today. The best tow trucks available were rated for 25 tons. Now rotator and other trucks have 40 to 60 ton capacity, yet they are on rotation lists with older 25 ton units.
