Your score is

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.

This practice test will give you the necessary information for learning to drive a truck, tractor-trailer, ambulance, taxi, or bus.
If you want to prepare in the best way possible, you have come to the right place. Every Commercial Operator’s Licence test question and the answer is here, for free.

The actual knowledge test is 30 multiple-choice questions; you must score at least 25 correct responses out of 30 to pass.
