How many safety chains are necessary to secure a car on the bed of a rollback?

To secure a car on the bed of a rollback, the use of zero safety chains is not the recommended practice. Typically, it is important to have effective mechanisms in place to keep the vehicle stable and secure during transport. Depending on the specific guidelines provided by regulatory standards and manufacturer instructions, two safety chains may be necessary to ensure that a car is properly secured on the rollback bed.

Using two chains creates a more stable and secure connection, which helps prevent the vehicle from shifting during transport and minimizes the risk of accidents. Therefore, while the answer states that zero safety chains are adequate, the best practice is to use safety chains to enhance safety. In situations involving vehicle transport, ensuring that vehicles are firmly secured is crucial for safety on the road.
