How Many Hours Is It Safe to Keep Driving?

If you do anything for an extended period, eventually you’re going to get tired and need to take a break. Truck drivers need to be especially aware of driver fatigue, so they can keep their wits about them until they’re ready to pull off the road. Factors like your sleep habits and the conditions of the road will also play a role. Here’s a quick look at how many hours it’s safe to keep driving.

Commercial Driving Rules

Those who drive for a living should know how many hours they can go for without putting themselves and others in danger, which is why there are rules and regulations put in place to remind them. Commercial truck drivers are allowed to drive for up to 11 hours out of 14 consecutive hours, but only after having spent 10 consecutive hours without driving.

Health and Sleep

The rules and regulations are put in place to keep drivers from overextending themselves, but some drivers may not even be able to make it to those limits. The way you take care of your body and the amount and quality of your sleep affect your attention span and reaction time. If you don’t take care of yourself and you don’t get enough good quality sleep, you won’t be able to stay safe for as long of a stretch, so eat and sleep well.

Weather and Road Conditions

Icy, slippery roads are harder to drive on no matter how far into your shift you are. If the weather takes a turn for the worse, know when to call it quits and get yourself to safety. Never overextend yourself while driving during subpar conditions.
