Following Distance & Stopping Distance Formulas

At 100 km/h, a vehicle travels 27.8 metres per second. A 2-second following distance equates to approximately 55.6 metres (rule of thumb: half the speedometer speed + 10% = 50 + 5 = 55 metres). Why other options are incorrect: • At least 25 metres (approximately 1 second).: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users. • At least 110 metres (approximately 4 seconds).: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users.

Under CBR driving standards and Article 55 RVV 1990, when taking the first exit (turning right) at a roundabout, you indicate right before entering and maintain it until you exit. Why other options are incorrect: • Indicate left upon entering, then switch to right while on the roundabout.: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users. • Do not indicate before entering; only activate the indicator while physically turning onto the exit ramp.: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users.

When proceeding straight ahead (second exit) on a roundabout, you do not indicate upon entering. You activate your right indicator immediately after passing the exit prior to the one you intend to take. Why other options are incorrect: • Before you drive onto the roundabout.: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users. • Immediately as your car enters the roundabout carriageway.: This decision increases crash risk and demonstrates inadequate traffic foresight under CBR standards. It fails to account for road hazards or vulnerable road users.
