Not only reactive but also I'll informed in their policies. They dont vote on policies based off knowledge of the industry they vote on policies that are profitable to them. E logs for example have proven to have had a direct correlation to the increase of accidents involving tractor trailers and they have actually made hours of service more lenient since then allowing on duty not driving to count Towards your half hour, split sleeper, etc because of this but yet keep them mandatory because it's a cash flow for them.

Thank you everyone
