Lane position, lane sharing and following distance
What the exam tests
This domain tests where to ride within a lane, when lane sharing is legal, and how much space to keep. A motorcycle is entitled to a full lane. Oklahoma does not authorize lane splitting between moving traffic or sharing a lane with a car. Ride where you can see and be seen, and change position as conditions change: the left portion often improves sight lines and oncoming visibility; the center can carry oil, grease, and wet spots; the right can help with wind or a left-turning vehicle but may put you near parked cars and driveways. Keep at least a two-second following gap in good conditions, and add time at night, in rain, on gravel, or with a passenger.
Worked example
A rider follows a truck at 55 mph. At 55 mph the motorcycle travels about 81 feet per second, so a two-second gap is roughly 162 feet. In rain, with reduced traction and visibility, two seconds is not enough; stretch to three or four seconds. If the truck stops suddenly, the rider needs both reaction time and stopping distance. The exam-style reasoning is: identify speed, convert to feet per second, multiply by seconds, then add margin for conditions.
Traps
Counting one second and calling it two; riding the oily center strip in traffic; sharing a lane with a car; lingering in a blind spot; and reducing space when a passenger or trailer changes stopping distance. Lane position is a tool, not a fixed rule.
