Rush Hour on I-25: A Two-Second Gap Is Not Enough
At 5:40 p.m. you are northbound on I-25 in Albuquerque near Comanche, riding a 2019 Kawasaki Versys 650. Traffic is moving 55–65 mph in three lanes, and the speed limit is 65 mph. You are in the center lane behind a pickup with dark tinted windows and an unsecured ladder in the bed. You are holding about 1.5 seconds' following distance-roughly 130 feet at 60 mph. The left lane is packed bumper-to-bumper. In the right lane, a silver SUV is merging from the Comanche on-ramp at about 45 mph. The pickup's brake lights flash, and it slows hard. You have not covered the brake lever. Your lane position is the center of the center lane, directly in line with the pickup's left rear corner.
1. What errors are already present before the pickup's brake lights flash?

The 1.5-second gap is too short for 60 mph. At that speed you cover about 88 feet per second, so 130 feet is only a second and a half; add perception and reaction time and the total distance needed is far longer. Riding directly in line with the pickup's left rear corner also hides the road ahead and puts you in the worst place to see around the tinted windows and ladder. Not covering the brake lever adds reaction time. The left lane is packed, so it is not a reliable escape route, and the merging SUV makes the right lane uncertain. The correct pre-incident setup is a three-second or longer gap, a lane position that lets you see past the vehicle, and fingers on the brake lever in heavy traffic.
2. What should you do at the moment the brake lights flash?
Read the worked answer
Squeeze both brakes progressively and keep the bike upright; do not grab the front brake or lock the rear. Because the left lane is packed and the right lane has a merging SUV, a blind swerve is more dangerous than controlled braking in your lane. Cover the brake earlier, check your mirrors for a clear escape, and prepare to stop if the pickup stops. If the right lane is clear behind the SUV, moving right may create space, but only after a mirror and shoulder check. Lane splitting is not legal in New Mexico, so filtering between the packed left lane and center lane is not an option.
3. How should you change your lane position and following plan for the rest of this commute?
Read the worked answer
Increase the gap to at least three seconds and, in heavy traffic, more. Ride in the left or right third of the lane rather than dead center so you can see around the vehicle ahead and be seen in its mirror. Avoid lingering in the pickup's blind spot, and do not follow a loaded truck closely enough that a dropped object or sudden stop leaves no escape. Keep the brake covered when traffic is bunched, scan two or three vehicles ahead, and identify an escape path before you need it. The goal is not to match the traffic rhythm but to preserve time and space that the lanes may not give you later.
