Driveway Pull-Out at 40 mph
You are riding a 400cc standard at 40 mph on a straight, dry two-lane road with a 45 mph limit. A car begins backing out of a driveway on your right, and its rear bumper blocks your lane about 65 feet ahead. The left lane is clear of oncoming traffic for roughly 350 feet, but a car is visible approaching beyond that. The right shoulder is only 3 feet of gravel before a drainage ditch. Your tires are good, brakes are stock and recently serviced, and you have about 0.8 seconds of reaction time before your hand and foot respond. You are not carrying a passenger. You are in the right third of your lane, and the car continues moving slowly backward.
1. Calculate roughly how much distance is used before braking begins and decide whether stopping in 65 feet is realistic.

At 40 mph you are traveling about 58.7 feet per second (40 × 5,280 ÷ 3,600). With 0.8 seconds of reaction time, you cover about 47 feet before the brakes even begin to work. That leaves only about 18 feet to the car. Even with good dry-pavement braking, a skilled rider needs roughly 70–100 feet of braking distance from 40 mph, plus reaction time. So a stop within 65 feet is not realistic. The correct conclusion is that braking alone will not avoid the collision; you must reduce speed and change direction, or find another escape path.
2. What maneuver do you execute, and what are the failure points?

Apply both brakes progressively to scrub speed, then, as the bike slows, release enough brake pressure to countersteer left into the clear oncoming lane. Do not swerve and brake at maximum at the same time; the tires have limited combined traction. Confirm the left lane is actually clear before committing. The oncoming car is beyond 350 feet, closing at about 80 mph combined; that gives roughly 3 seconds, and a swerve takes about a second, so the margin is tight but usable if the car is truly that far away. Failure points: grabbing the front brake and losing the front, target-fixating on the car, swerving into the oncoming car, or drifting right into the gravel and ditch. If the backing car stops and clears your lane, straighten and continue; if it keeps coming, the left lane is the better gap.
3. If the left lane were blocked by an oncoming car 150 feet away, what is your plan?
Read the worked answer
Do not swerve into the oncoming lane. At a combined closing speed near 80 mph, 150 feet is under 2 seconds-less than the time needed to set up and complete a safe swerve. Your best option is hard, progressive braking while staying in your lane, aiming for the gap behind the backing car if it continues to move, or stopping before the car if it clears. If impact is unavoidable, reduce speed as much as possible and avoid a head-on with the oncoming vehicle; a controlled low-speed impact or a path into the gravel may be less severe than crossing into traffic. The key is to choose the least-bad path early and not freeze.
