High Beams and a Dark Pedestrian
At 22:30, a driver is on a rural two-lane road posted 55 mph with a 40-foot trailer and 72,000 lb GCW. High beams are on and the windshield is clean. An oncoming pickup with bright headlights and two auxiliary lights approaches and does not dim until about 400 feet away. The driver is dazzled and can see little beyond the right fog line. After the pickup passes, the driver's eyes are still adjusting when a pedestrian in dark clothing appears in the driver's lane about 200 feet ahead, walking away from the truck. The shoulder is narrow and soft, and there is oncoming traffic behind the pickup. The driver's loaded stopping distance at 55 mph is far longer than 200 feet. The driver has air brakes and anti-lock brakes.
1. What should the driver have done as the oncoming vehicle approached, and why?
Read the worked answer
Oncoming glare should be handled before it becomes an emergency. Dim the truck's high beams at least 500 feet before meeting the vehicle, even if the other driver does not. Do not stare at the lights; look down and to the right edge of the lane to hold position. Slow down as soon as the glare makes the lane uncertain, because the driver is effectively blind for a few seconds. Flashing high beams back is a bad trade: it makes two drivers blind. Keeping low beams and a reduced speed gives the driver time to recover and react to whatever the lights were hiding.
2. Now that the pedestrian is 200 feet ahead, what are the driver's options and priorities?
Read the worked answer
At 200 feet with a loaded 72,000-lb rig at 55 mph, a stop is not possible. The driver should brake firmly and progressively, sound the horn, and hold the lane until the left lane is clearly open; a blind swerve into oncoming traffic or a soft shoulder can be worse. ABS allows steering while braking, but it does not shorten physics. If the left lane is clear, a controlled move left may give the pedestrian room. If not, the priority is to reduce speed and warn the pedestrian. This is why the speed should already have been lower when visibility was reduced by glare.
3. What speed and scanning practices would prevent this situation?
Read the worked answer
At night, the truck should never be driven faster than the distance lit by the headlights and the distance the driver can stop in. High beams help, but glare, curves, and dark-clothed pedestrians shorten useful sight distance. The driver should scan the right edge and the lane ahead, use high beams whenever traffic allows, keep the windshield and lights clean, and slow near areas where pedestrians or animals may appear. A speed that works in daylight is not automatically safe at 22:30. If 200 feet is the realistic sight distance, 55 mph is overdriving the headlights.
