Deer, Gravel, and a Dark Curve
Marisol has been riding for three months on a 650cc twin. It is 9:40 p.m. in October and she is on a rural two-lane Pennsylvania route posted 55 mph, heading home with 40 miles to go. Her only headlight is a stock 55/60-watt halogen, and her face shield is a lightly tinted one she bought for daytime use. A yellow warning sign shows a 25 mph curve, and the curve tightens near the exit. Just past the sign she sees a patch of loose gravel spread across the right half of her lane, and a pair of deer eyes reflecting at the outside edge of the curve about 80 feet ahead. A pickup behind her has been following at roughly one car length for the last two miles. She is already at 50 mph, and the curve entry is about 150 feet away.
1. What should Marisol do in the next few seconds, and in what order, given the gravel, the deer, and the closing curve?

Speed is the first problem, not the deer. At 50 mph she is carrying twice the speed the curve is signed for, and the gravel removes most of her braking and steering grip once she is on it. The order should be: roll off the throttle and apply both brakes smoothly while the bike is still upright and on clean pavement, getting well below 25 mph before the gravel; then cross the gravel with the bike as upright as possible, no abrupt braking and no sharp steering inputs; then look through the curve to the exit and press the inside bar to lean. The deer should be handled by covering the brakes and slowing further, not by swerving. At 80 feet a swerve on gravel risks a low-side or a trip into the oncoming lane, and deer often move at the last second. If the deer stays at the edge, slow to a crawl or stop; if it moves, brake in a straight line.
2. How should she handle the tailgating pickup while she manages the curve?

She should not let the truck dictate her speed. Brake-checking a tailgater at night is a good way to get rear-ended, and speeding up to create a gap only means entering a 25 mph curve even faster. The useful move is to build a buffer ahead of herself by increasing her following distance to any vehicle in front, so she can slow gradually instead of abruptly. She should also signal early and consistently so the truck can read her intentions, and tap the brake light a few times to make her slowing visible before applying real braking. After the curve, if the truck is still glued to her, she should pull off at a wide, well-lit spot and let it pass rather than ride 40 miles with it on her fender.
3. What should she have done differently before this ride, and what should she do about the tinted shield?
Read the worked answer
A lightly tinted shield at night cuts the light she most needs; it is a daytime item and should have been swapped for a clear shield or goggles before dark. The stock 55-watt headlight is adequate only if it is clean and aimed correctly, and even then it does not light enough road for 55 mph. At night, particularly in deer country, the correct speed is the one from which she can stop within the illuminated distance - often 10–15 mph below the posted limit. Before the ride she should have checked the shield, cleaned and aimed the headlight, and picked a route and pace appropriate to a rider with three months of experience. The takeaway is not that she needs better equipment; it is that she was riding faster than her sight distance and experience allowed.
