A variety of car rental options are available in Chiang Rai. International car rental companies like Budget, National and Avis have offices in Chiang Rai.
There are local companies also. However, it should be kept in mind that many local companies do not provide insured vehicles. In such cases, the cost of the damages incurred (if any) has to be borne by the renter.
The option to hire local drivers along with the cars is available; they can also be helpful when crossing the police check points located near the border.
Tourists can also opt for motorcycle rentals but a helmet and a valid driving license is required.
