A method includes accessing information stored for positions along a road and using the accessed information to identify an expected trajectory for a vehicle. Position information for the vehicle is received from a global positioning system for two different time points and is used to determine a trajectory of the vehicle. The trajectory of the vehicle and the expected trajectory are used to determine a lateral offset of the vehicle from the expected trajectory and the lateral offset is used to determine when to issue a lane departure warning for the vehicle.
