Following Distance on the Railway Trail Link
You are riding a scooter along a two-lane road at 40 km/h behind a small truck loaded with loose gravel. The truck's tailgate is not secured and small stones are bouncing out at irregular intervals. You are about one second behind it, because you moved up to avoid a tailgating taxi behind you. The road ahead has a shallow right bend and a bus stop where a bus is indicating to pull out. Your visor has a smudge of road spray on the left side, and the sun is low behind you, so the truck's rear is in shadow.
1. Assess your following distance and the hazards the truck presents.

One second at 40 km/h is far too close - you are covering roughly 11 metres per second, and a falling stone gives you almost no reaction time. The loose gravel is a debris hazard that can crack a visor, chip paint, or cause a reflex swerve; the unsecured tailgate means the volume of debris could increase suddenly. The shadowed rear of the truck hides its brake lights and any hand signals, and your smudged visor reduces your view of the left side, which is exactly where the bus will emerge. The correct following distance in dry conditions is at least two seconds, and with debris and poor visibility you should be at three or more - roughly 35 metres. Drop back smoothly rather than braking hard, so the taxi behind has time to adjust.
2. The taxi behind is still close. How do you manage that pressure without compromising your safety?
Read the worked answer
You cannot let a tailgater dictate a dangerous gap to the truck. If you stay close to the truck to appease the taxi, you inherit the truck's stopping distance plus your own reaction time, and the gravel gives you no margin. Instead, increase the gap to the truck and give the taxi a clear, early signal of what you are doing: a brief brake-light tap before you slow, then a steady reduction. If the taxi remains glued to you, consider pulling over at a safe spot - past the bus stop, not into it - and letting it pass. That costs seconds and removes the pressure. Never speed up into the debris zone to create space behind you; the hazard in front is the one that will hurt you first.
3. The bus begins to pull out. What is your plan?
Read the worked answer
The bus is indicating, so it intends to move into your lane, and you should expect it to do so even if it has not yet moved. Your plan depends on the truck: if the truck brakes for the bus, you need the gap you have just created to stop behind it. If the truck continues and the bus waits, you still should not overtake the bus on its right as it pulls out. Reduce speed, cover the brakes, and watch the bus driver's window for eye contact. If the bus does pull out, yield - a bus re-entering traffic has limited visibility and a long stopping distance. Once it is established in the lane, hold back until you can see past it, and only then consider a pass with full clearance.
