Driving Techniques and Road Behaviour
Core Concepts
Safe driving techniques include observation, anticipation, and smooth control. Key concepts: the two-second rule for following distance (double in rain, triple in snow), proper use of mirrors and blind spot checks, and defensive driving. In Bulgaria, you must drive on the right; overtaking is on the left. Use of seat belts is mandatory for all occupants. Headlights must be on at all times outside built-up areas and in poor visibility. Alcohol limit is 0.05% BAC (0.00% for novice drivers). Mobile phone use is prohibited unless hands-free.
Traps in Questions
- Following distance: Questions may ask for the minimum distance in seconds. Remember: 2 seconds normal, 4 seconds in rain, 6 seconds in snow.
- Overtaking: You must not overtake if you cannot see far enough ahead, or at pedestrian crossings, intersections, or railway crossings.
- Roundabout signalling: Signal left when entering if you intend to turn left, signal right when exiting.
- Emergency vehicles: You must yield to vehicles with flashing blue lights and sirens; do not follow them closely.
Worked Example
You are driving at 90 km/h on a rural road. What is the minimum following distance in metres? Using the two-second rule: distance = speed (m/s) × time. 90 km/h = 25 m/s. 25 × 2 = 50 metres. In rain, it would be 100 metres.
Rule of Thumb
"Only a fool breaks the two-second rule." Increase distance in bad weather. Always check mirrors before braking or turning.
