Oklahoma driving lesson · Lane Usage and Maneuvers
Lanes and changing lanes
A 3-minute lesson from the Oklahoma course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
A lane is the part of the road wide enough for one line of vehicles. Most paved lanes are marked with white or yellow lines, but on dirt or gravel roads, some rural roads and private drives the lanes may be unmarked. They are still there, and you must drive in the proper one.
Lane
Part of a roadway wide enough for a car or a single line of vehicles to travel safely. You must always drive in the proper lane, whether it is marked or not.
On a four-lane road you want to move left. Check ahead and behind, check your mirrors, signal left, look over your left shoulder, look behind to both sides again, and make sure no car sits in your blind spot. Then move over smoothly and cancel your signal.
