One of the most important regulations is the mandatory use of seat belts, which applies to all passengers in the vehicle. Quebec also has specific regulations governing the speed limits for commercial trucks and buses, with lower speed limits in place when driving in urban areas or near residential areas. Additionally, operators of commercial vehicles must maintain proper distance between vehicles, observe all traffic signals, and avoid driving under the influence of drugs or alcohol. Failing to comply with these regulations can result in severe penalties, including hefty fines, license suspension or revocation, and possible jail time. Commercial drivers must know these traffic rules to operate their vehicles safely and responsibly.
