Yes, drivers of tractor trailers, 18-wheelers, large buses, and other large trucks must abide by the Hours of Service (HOS) regulations. These vary depending on the size of vehicle and type of cargo. For example, a driver of a commercial bus carrying 20 passengers is allowed to drive a maximum of 10 hours after 8 hours of rest.
Are there rules governing how long a Tractor Trailer or 18-wheeler truck driver can be behind the wheel before he has to stop for a break or to rest?
