CDL Vehicle Combination Practice Test

What is the safest way to turn without entering another traffic lane?

1. Check mirrors frequently

2. Turn sharply

3. Turn wide as you complete the turn

4. Honk before turning

The correct answer is: Turn wide as you complete the turn

The safest way to turn without entering another traffic lane is to turn wide as you complete the turn. This method allows you to maintain control of your vehicle while ensuring you do not encroach on adjacent lanes or put other road users at risk. By making a wider turn, you decrease the risk of clipping the curb, colliding with barriers, or interfering with other vehicles that may be traveling next to you. This approach is especially important for larger vehicles, which have a longer wheelbase and require more space to maneuver safely. A wider turn improves visibility and gives you a better view of any oncoming traffic, pedestrians, or obstacles, reducing the possibility of accidents. Checking mirrors frequently is certainly important for overall safety and awareness of your surroundings, but it does not specifically address how to turn without entering other lanes. Turning sharply increases the risk of losing control and may cause the vehicle to sway or skid, which is dangerous, particularly for combination vehicles. Honking before turning can serve as a warning to other drivers, but it does not impact the physical execution of the turn itself and should not be relied upon as a primary safety measure.
