Zorluk: OrtaSeparation Distances and the Two-Second Rule

You are driving behind another vehicle on a dual carriageway in good, dry conditions. To ensure you are maintaining a safe separation distance using the two-second rule, what should you do?

  1. A
    Maintain a fixed gap of one car length for every 10 mph of your travelling speed.
  2. B
    Allow a minimum four-second gap from the vehicle ahead on dry roads to account for reaction time.
  3. Note when the vehicle ahead passes a fixed roadside object and ensure at least two seconds elapse before your vehicle reaches it.Cevap
  4. D
    Keep close enough to ensure you can clearly see the rear tyres of the vehicle ahead touching the tarmac.

Cevap

Note when the vehicle ahead passes a fixed roadside object and ensure at least two seconds elapse before your vehicle reaches it.
In good, dry road conditions, drivers should maintain at least a two-second time gap behind the vehicle ahead. This is measured by choosing a fixed reference point (such as a bridge or road sign); when the vehicle in front passes that point, at least two seconds must elapse before your vehicle reaches the same point.

Adım Adım Çözüm

1
Identify a stationary reference point ahead
A fixed marker such as an overhead bridge, signpost, or lamppost is selected.
A stationary object provides an unmoving benchmark to measure time separation.
2
Start counting when the lead vehicle passes the reference point
Count 'one thousand and one, one thousand and two' (two seconds).
This measures the time interval between the two vehicles passing the exact same spot.
3
Assess your vehicle's position upon finishing the count
If you reach the marker before finishing the two-second count, you are too close and must increase your following distance.
A two-second gap ensures sufficient thinking and braking distance under normal dry conditions.

Anahtar Kavram

The two-second rule provides a time-based safety margin on dry roads, verified using a stationary roadside marker.
