Tailgater, Glare, and a Night Work Zone
It is 10:15 p.m. on I-96. You are in the right lane at 65 mph with low beams on. A lifted pickup with very bright headlights has been sitting about 1.5 seconds off your rear bumper for two miles, and its light is bouncing off your mirrors straight into your eyes. Ahead, an arrow board shifts traffic to the left and orange barrels pinch off the right lane; a sign reads SPEED LIMIT 45 and FINES DOUBLE IN WORK ZONE. A semi is pacing you in the center lane with its trailer about even with your front fender. In the closed right lane ahead, a state police cruiser sits with its roof lights flashing.
1. How do you handle the pickup behind you without making things worse?
Read the worked answer
A 1.5-second gap at 65 mph is roughly 145 feet - well inside the 3-second minimum and far short of what you need at night. But your options are limited by the semi alongside you.
- Do not brake-check and do not speed up. Brake-checking invites a rear-end crash you will be blamed for; speeding up just moves the problem and puts you deeper into the work zone taper.
- Create space ahead by easing off the throttle slightly so you have room to brake gradually rather than suddenly.
- Fix the glare: flip the interior mirror to its night position, and do not adjust your speed because you feel crowded.
- Signal and move to the center lane once the semi has cleared. If the pickup keeps tailgating after that, take the next exit and stop somewhere well lit rather than staying in front of it.
2. What do the work zone signs and the arrow board require of you, and what is the real hazard beyond the lower number?
Read the worked answer
The 45 mph posting is a legal limit, not a target for a work zone at night.
- Obey 45 mph and expect doubled fines for moving violations in the zone. Workers or equipment may be just past the barrels where you cannot see them.
- The arrow board means your lane is ending. Merge at the first reasonable gap rather than racing down the closed lane to the taper - that is where work zone sideswipes happen.
- The real hazard is speed differential. You at 65 and the semi at 55 with barrels ahead means a closing rate that eats your reaction time. Slow early, pick a gap, and commit.
- Resist the glare of the arrow board and the cruiser's lights. Staring at flashing lights draws you toward them; aim your vision at the lane edge and your intended path.
3. The state police cruiser with flashing lights is stopped in the closed right lane ahead. What does Michigan require of you, and how does it apply here?
Read the worked answer
Michigan's Move Over law applies to stopped emergency vehicles, tow trucks, and road-service or maintenance vehicles displaying flashing lights.
- If a lane is available, move over at least one lane away from the stopped vehicle.
- If moving over is not possible or not safe, slow to at least 10 mph below the posted speed limit and pass with caution.
- Here you are already boxed in by the semi and a narrowing work zone, so the move-over option may not exist. The fallback is the one that matters: reduce speed well below 45, hold a steady line, and do not stare at the lights.
Remember that in a work zone the posted limit is already reduced - slowing '10 below' is measured against the limit in effect, which is 45, not 65.
