Cdla Hazmat Training.
I needed a refresher to renew my hazmat after letting it lapse 5 years ago. Not only did I get a refresh, driving-tests.org helped me ace my written test! The individual test prep, funny hints and ease of using this format is incredible! It's really simple, pay your money, put in the work of studying and once you've completed all your curriculum, they send your info to FMCSA. Thank you for this platform!

This is the only thing you need!
I've used this program everytime I need to add or upgrade and passed every time. I only had 7 days when I found out I needed a ELDT certificate for Hazmat, and was going for Doubles Triples, Tanker, and Hazmat. I passed all three with only 2 wrong answers. I recommend this to anyone doing anything with your CDL or DL.
