The Saint Christopher and Nevis Licensing Authority (Traffic Department) of the Royal Saint Christopher and Nevis Police Force is tasked with the responsibility of administering Driver and Vehicle Licences and is empowered under the Chapter 15.06 Vehicles and Road Traffic Act. The Licensing Authority works closely with the Inland Revenue Department which issues both the drivers licence card and the vehicle licence decal, after payment of the appropriate fees.
Following are the procedures that govern renewal of driver licences. While this site gives you a brief outline of the basic rules and guidelines, you should also read the Chapter 15.06 Vehicles and Road Traffic Act to get a proper understanding of the mandate of the Licensing Authority. The act also specifies the various fines for persons who try to circumvent the law and clearly identifies the responsibilities of vehicle owners.
It is important to note that to operate a vehicle, both the driver and the vehicle must be licenced and the vehicle is always driven on the left side of the road. There are no exceptions to these rules.
