If you are carrying Division 1.2 or 1.3 materials, how far away must you park from the traveled portion of the roadway?

Remember to use your judgement about speed limits, they are a maximum, not compulsory. Rely on your own judgement, not a sign.

You can expect it to take more than 15 seconds for a regular tractor-trailer to clear a double track, and 14 seconds to be safely over a single track.

There is absolutely zero tolerance for CDL drivers who use any vehicle in the commission of a felony that involves the movement or making of controlled substances. Regardless of the vehicle driven, you will lose your CDL privileges for life. Times are tough, but no matter what the pay, don't move cargo for bad people. If you are threatened, go to law enforcement.

In an emergency (not just a hazard) stop your vehicle as soon as safe to do so and think calmly about the best action to take.

Cleaning up a spill, a huge contamination in particular, is very expensive. Therefore, if you notice a leak, stop as soon as you possibly can and get off the road. Stay with your vehicle because of liability and safety issues and send someone else for help. You will need to send a large amount of vital information, including your location, your direction of travel, the hazard class and ID numbers, your carrier's location, and the cargo's destination. Make sure you write it all down for the person seeking help.
