Swivel seats are primarily designed to assist with entering and exiting a vehicle and can be used in the driver position if that matches the needs of the individual. Swivel seats typically have locking mechanisms to secure the seat in place when the vehicle is in motion. The purpose of these mechanisms is to prevent unintended rotation or movement that could compromise the driver's control of the vehicle. It is crucial to comply with local traffic laws and regulations regarding vehicle modifications and adaptations. It is important to work with a mobility dealership that has trained and certified technicians that can safely install swivel seats in the desired position.
