One important rule is for drivers to maintain a safe following distance between themselves and the vehicles in front of them. This helps prevent accidents and provides more reaction time in case of sudden stops or changes in traffic flow. Additionally, commercial drivers must obey posted speed limits and traffic signals and remain alert to avoid distracted or impaired driving. Failure to adhere to these rules can result in serious consequences, including fines, license suspension, or criminal charges. Commercial drivers must prioritize road safety and comply with all applicable traffic laws.
