  1. ACover the clutch and brake, and be prepared for the light to change or for cross-traffic to enter.
  2. BIncrease speed to clear the intersection quickly before the light changes.
  3. CMaintain speed and proceed through the intersection, assuming the light will remain green.
  4. DLook only straight ahead to focus on the green light.
Show answer & explanation

Correct answer: A. Cover the clutch and brake, and be prepared for the light to change or for cross-traffic to enter.

Approaching a 'stale' green light requires extra caution. Covering the clutch and brake prepares you for a sudden stop or adjustment, anticipating potential hazards like the light changing or a vehicle running a red light from the cross street.

Why the other options are wrong

  • B. Increasing speed reduces reaction time and increases the severity of any potential collision.
  • C. Assuming the light will remain green is a dangerous practice and reduces reaction time.
  • D. Tunnel vision is dangerous; scanning the intersection for hazards is essential.

Stale Green Light

A traffic light that has been green for a significant period and is likely to change soon. It requires motorcyclists to be extra cautious and prepare to react.

  • Anticipate a change to yellow or red.
  • Be ready for cross-traffic.
  • Cover controls for quick reaction.

Memory trick: Stale Green: Scan, Slow, Prepare to Stop.
