Stale Green and a Blocked Box on the Road Test
You are six miles into the road test route in a 40-foot transit bus, examiner in the right seat. Westbound on a four-lane arterial posted 40 mph, you are holding 38 mph. The signal ahead has been green since you crested a rise about 350 feet back - you have never seen it change. Traffic beyond the intersection is stacked: a left-turner waiting in the inside lane, and three cars stopped bumper to bumper in your lane, the last about 60 feet past the stop line. The intersection is roughly 70 feet wide curb to curb. A pickup is following you at about a 1.5-second gap and is not dropping back. Your bus is 40 feet long; the light is now 120 feet ahead.
1. At 350 feet and again at 120 feet, what is your decision process?

The stale green is a warning, not a permission slip. The rule is not 'the light is green so go' - it is 'do not enter unless you can clear.'
Run the arithmetic on the space you need: 40 feet of bus, plus 70 feet of intersection, plus a safe gap behind the stopped car. That is roughly 120 feet of clear pavement past the stop line before you are legally and physically out of the box. What is actually there is about 60 feet and a stopped car. If you enter, you stop with 40 feet of coach hanging in the crosswalk and the intersection - blocking the box, blocking cross traffic, and in a road-test context an automatic failure.
At 350 feet: recognize the stale green, ease off the throttle, cover the brake, and build a plan to stop at the line. Do not accelerate to 'make it.' Losing five seconds is free.
At 120 feet: with the queue not clearing, you should already be decelerating and preparing to stop before the stop line. Check the cross street for the left-turner and anyone running the light, check the mirror for the tailgater, and apply the brake early and progressively so the pickup behind has time to react.
2. The light turns amber when you are 60 feet from the stop line. What do you actually do, and what does that reveal about the earlier decision?
Read the worked answer
At 38 mph you are moving about 56 feet per second. A loaded 40-foot bus needs roughly 200–250 feet to stop from that speed once you count reaction time and air-brake lag. At 60 feet, stopping before the line is not available to you without standing on the brakes - which, with a tailgater 1.5 seconds back, invites a rear-end collision into a bus full of people.
So you are committed, and the honest answer is: proceed through and manage the outcome. Enter, brake firmly but progressively, keep the wheels straight so the bus tracks straight, and stop as far forward and as square as the queue allows - behind the last car, not in the crosswalk if there is any choice. Do not swerve into the turn lane to find room.
What it reveals: the trap was set 290 feet earlier. A driver who slows at a stale green arrives at that same 60-foot point at 20 mph and stops comfortably. A driver who holds 38 mph because the light is green gets forced into a commitment they did not choose. The examiner is watching the decision at 350 feet, not the panic at 60.
3. How do you handle the pickup that is sitting 1.5 seconds off your bumper?
Read the worked answer
You cannot control the pickup; you control what the pickup sees and how much room you leave.
- Signal early and brake early. Light pressure on the pedal well before you need to slow gives the brake lights time to register. Waiting until the last moment is what turns a tailgater into a collision.
- Do not brake-check. A brake tap to warn is one thing; a hard jab with 40 feet of bus and 47 seats is how you get hit.
- Increase your own following distance to the vehicle ahead - with a tailgater behind, the buffer in front is your only crash-avoidance space. If the pickup stays glued, open the gap further and reduce speed slightly so your own stop is gentler.
- Leave an out. Know the shoulder or the next lane before you need it, and keep your mirrors in the scan.
- Do not let the tailgater push you into the intersection on the amber. The pressure to 'go' so the pickup does not hit you is exactly how drivers end up blocking the box.
