Oklahoma driving lesson · Lane Usage and Maneuvers
Entering, leaving and stopping on the expressway
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.
Most expressway mistakes happen at the edges: merging in, getting off, or stopping on the shoulder. Plan your entrance, direction and exit ahead of time, keep a following cushion, and never make last-minute moves.
Avoid collisions: drive with caution
Plan your entrance, direction and exit as far as possible
Stay 3 seconds behind the vehicle in front; allow 4 seconds in bad weather
Watch 15-20 seconds ahead for cars braking, entering and exiting
Observe all highway signs; move to the exit lane as early as possible
Never turn around on the expressway. Do not, under any conditions, cross the median or divider to turn around on a controlled-access highway; drive to the next exit, get off, and re-enter going the other way.
Don't slow down on the expressway itself before exiting; slow down after turning into the deceleration lane. Don't make a last-minute turnoff, and check the posted safe speed for the ramp.
You miss your exit. Don't brake, back up or cut across the median. Continue to the next exit, get off, and re-enter the expressway in the other direction.
