Now is the time of the year to constantly check your air lines connecting the truck to the trailer. If they are plastic, they can kink or break if they hang up on your flap hanger while turning. Make it part of your walk around, your load securement check, your pre and post trip inspection to visually inspect them. It is also a good time to inspect while getting loaded or unloaded. If your hoses are rubber like on a log truck inspect for areas that may have been rubbed on the road.
