You want drivers to do the daily trip inspections so that you have the report of any maintenance issues as soon as possible. Then you can make any repairs as soon as possible. Safe trucks mean you don’t endanger your driver, or others on the road.
A peace officer can ask to see your trip inspection. By law, you must be able to produce one for that day.
If your truck is inspected and found to have a maintenance issue, it could get an out-of-service order. But if you keep your fleet running well, you won’t suffer those delays.
It only takes a day for some maintenance issues to arise. For example, a tire that was at full pressure when you checked it post-trip can still go flat overnight.
