Can your Car be flat towed?

Not all cars can be flat towed. Some vehicles need the continuous operation of a pump within the transmission to keep certain parts lubricated, otherwise, the transmission can become damaged. However, some vehicles can be flat towed without any issues. Most front-wheel drive, manual transmission vehicles don't need modifications to be flat towed.

  • Always check your owner's manual to determine whether it is suited for flat towing. 
  • Refer Waka Kotahi/NZ Transport Agency factsheet 75.
  • The owner of the vehicle is to contact franchise dealerships to confirm if the vehicle can be flat towed.  Tow bar specialists will have a scope of vehicles that can be automatically confirmed for flat towing. Franchises/Tow Bar experts will have the final decision if a vehicle can have an A-frame installed.
