  3. Intersections and turns3 of 20

    How far in advance must an Oklahoma driver continuously signal before turning, slowing down, or stopping?

    The answer

    Answer: B. Oklahoma law requires drivers to signal continuously for at least 100 feet or one-third of a city block before turning, slowing down, or stopping. Signaling well in advance alerts following and oncoming motorists of your intentions, giving them adequate time and distance to adjust speed and prevent rear-end collisions.

At an uncontrolled intersection where two vehicles arrive at approximately the same time, Oklahoma law requires the driver on the left to yield the right-of-way to the driver on the right. Both drivers should approach cautiously, slow down before entering the crossing, and never assume the other driver will stop.

    The answer

    Answer: C. Under the Oklahoma Driver Manual, the recommended safe speed when executing a turn is 10 miles per hour or less. Reducing your vehicle's speed before turning gives you full steering control, prevents tire skidding, and allows you to watch for pedestrians crossing the side street.

    The answer

    Answer: C. Oklahoma law requires that when passing on a two-lane road, the driver must verify that the road ahead is clearly visible and free of oncoming traffic for a distance of at least 200 feet before beginning the pass.

  14. Passing lane usage14 of 20

    When passing another vehicle on a two-lane highway, when is it safe to return to your original right lane?

    The answer

    What is the minimum legal parking distance from a crosswalk at an intersection in Oklahoma?

    The answer

    Answer: B. Oklahoma law prohibits parking a motor vehicle within 20 feet of a crosswalk at an intersection. Maintaining this clearance ensures that approaching motorists have an unobstructed view of crossing pedestrians and that pedestrians can clearly observe oncoming roadway traffic before stepping off the curb into the roadway.

  19. Emergencies safety19 of 20

    When driving at night in Oklahoma, within how many feet of an oncoming vehicle must you dim your high beam headlights?

    The answer

    Answer: C. When driving at night in Oklahoma, you must dim your headlights to low beam whenever you are within 1,000 feet of an oncoming vehicle. High beams produce intense glare that temporarily blinds approaching motorists, dramatically increasing the hazard of head-on collisions on dark two-lane roads.

    Source: OK Driver Manual — Chapter 11: Driving Tips (p. 59)

  20. Emergencies safety20 of 20

    When following another vehicle at night in Oklahoma, within how many feet must you dim your high beams to low beams?

    The answer

    Answer: C. Oklahoma law requires drivers to switch their headlights from high beams to low beams when following within 600 feet of another vehicle traveling in the same direction. High beams reflect off the interior rearview and side mirrors of the leading car, impairing the front driver's vision and nighttime focus.
