Lines that travel along the road (longitudinal) inform and warn drivers of approaching situations that will need them to do something - like turn right, or do not cross. Lines that cross the road (transverse) give instructions to road users like 'give way' or 'stop'. A broken white line marks the middle of the road.

White lane markings are the most common. Solid white lines define lanes of traffic going in the same direction, or they show you the location of the shoulder of the road. Broken or “dotted” white lines are used to show the center line between lanes. Yellow lines show you where traffic is going in different directions.
