Following a Truck on a Wet Highway
You are riding behind a flatbed truck on a four-lane highway at 60 mph. It is raining lightly, and the road surface is wet but not flooded. The truck is loaded with loose gravel and has no mud flaps on the rear. You are 1.5 seconds behind it. Your visor is beaded with rain and you can see the truck's taillights but not its tires. The truck's driver is drifting slightly within the lane. You plan to pass. There is a car approaching in the left lane about a quarter mile back.
1. Evaluate your following distance and position, and identify the specific hazards.

At 60 mph, 1.5 seconds is far too close, especially in rain: wet pavement lengthens stopping distance and reduces traction, and the two-second minimum should be expanded to three or four seconds in rain. The truck is shedding loose gravel with no mud flaps, so you are in the debris path - gravel can strike your face, crack a shield, or cause a front-tire slip. The spray from the truck's tires reduces your visibility, and you cannot see its tires, which means you cannot read its traction or detect a tire problem. The driver drifting within the lane is a warning sign of possible impairment, distraction, or fatigue, so you should treat the truck as unpredictable.
2. Should you pass now? Walk through the decision.

Not yet. The left-lane car is a quarter mile back - at closing speeds that gap can shrink quickly, and a pass at 60 mph requires you to accelerate, spend time alongside the truck, and return to the lane. In rain, acceleration and lane changes are less forgiving. Before passing you should: increase following distance to at least three to four seconds to get out of the gravel and spray, confirm the left lane is clear for a sufficient distance (check mirror and head-check), signal, and then pass decisively and smoothly, spending minimal time in the truck's blind spot. Because the truck is drifting, do not linger beside it; complete the pass or drop back. If the left-lane car is closing, wait until it passes, then reassess.
3. What should you do about your rain-beaded visor before and during the pass?
Read the worked answer
Rain-beaded visors scatter light and hide hazards, so clear it before initiating a pass: use a glove squeegee or a treated shield, and if you cannot see clearly, do not pass. A visor that fogs or beads at 60 mph in traffic is a visibility emergency. Turn your head slightly to use the airflow to clear it, keep a clear shield rather than a tinted one in rain, and consider an anti-fog insert. Never take a hand off the bars to wipe the shield mid-pass; clear it when you have space and time.
