When making a turn, is it acceptable to shift gears?

When making a turn, it is generally advised not to shift gears. This is primarily because shifting gears can cause a momentary disruption in the vehicle's balance and traction. During a turn, maintaining the proper speed and control is crucial; if you shift gears, it may lead to a loss of power to the wheels or an unexpected change in speed, which can destabilize the vehicle.

Additionally, turning involves steering dynamics and vehicle momentum that can be adversely affected by shifting, especially in larger vehicles associated with Class A CDLs. The vehicle's weight and size make it even more critical to ensure that you are settled in the correct gear prior to initiating the turn. By keeping a consistent gear before entering the turn, you enhance safety and maintain better control throughout the maneuver.
