Road Traffic Act and Traffic Regulations (Færdselsloven)

  • Færdselsloven §3: All road users must behave with due care and caution; drivers must be able to stop in the distance visible ahead.

  • Bus with trailer is a combination; maximum permitted speed on motorways is 80 km/h unless lower limits apply, and on other roads outside built-up areas 70 km/h (check current regulations).

  • Right-hand traffic; overtaking on the left is the rule. Overtaking on the right is only allowed in specific situations (e.g., queues, trams).

  • In built-up areas, speed limit is 50 km/h unless otherwise signed. On motorways, general limit is 130 km/h for cars, but lower for buses with trailers.

  • Seat belts must be used if fitted; passengers in buses must be informed. Children under 135 cm require approved child restraints in vehicles where such exist.

  • Driving under the influence: blood alcohol limit is 0.5 g/L (0.05%). For professional drivers, stricter rules may apply; suspension of driving licence is possible.

  • At pedestrian crossings, drivers must yield to pedestrians. In bus with trailer, remember increased stopping distance and blind spots.

  • Use of mobile phone while driving is prohibited unless hands-free and used safely. Professional drivers must comply with tachograph and rest rules.

  • Accident reporting: If involved in an accident with personal injury, stop, help, and call emergency services. Exchange information with other parties.

Vehicle Combination and Coupling: Bus with Trailer, Weights, Dimensions and Load

  • Maximum authorised mass (MAM) of a bus with trailer combination must not exceed 18,000 kg (or higher if approved by vehicle registration).

  • Trailer MAM must not exceed the bus's towing capacity as specified by the manufacturer. Check the vehicle registration document.

  • Maximum width: 2.55 m for standard vehicles; 2.60 m for refrigerated vehicles. Maximum height: 4.0 m. Maximum length: bus 12 m (or 15 m articulated), trailer 12 m, combination 18.75 m (or 25.25 m for specific combinations).

  • Coupling: Ensure trailer is securely attached; use safety cable for breakaway. Check lights, brakes, and tyre condition of trailer.

  • Load must be secured to prevent shifting; use straps, nets, or other approved securing devices. Load must not exceed axle weights or gross vehicle weight.

  • Passenger safety: In a bus, all passengers must be seated or standing in designated areas; aisles and exits must be clear. In trailer, passengers are not allowed unless specially designed and permitted.

  • Weight distribution: Load should be evenly distributed; too much weight on rear axle can affect steering and braking. Check axle load limits on registration document.

  • Trailer braking system: Must be compatible with bus; check connection and function before driving. For trailers over 750 kg, overrun or power brakes required.

Driving Technique and Handling of a Bus with Trailer (Turning, Reversing, Braking, Stability)

  • Turning: Account for off-tracking (rear wheels cut inside). Use wide turns to avoid hitting kerbs or obstacles; check mirrors for trailer swing.

  • Reversing: Use mirrors and if possible a guide. Reversing with trailer requires steering opposite to desired direction of trailer; practice in safe area.

  • Braking: Increase following distance due to longer stopping distance. Use engine brake and retarder to reduce brake fade. Avoid sudden braking on curves.

  • Stability: High centre of gravity and trailer can cause rollover risk. Reduce speed in curves and avoid abrupt steering. Load heavy items low.

  • Hill starts: Use parking brake or hill-hold to prevent rolling back. Ensure trailer brakes are applied when parked.

  • Wet or slippery roads: Reduce speed, increase distance, avoid cruise control. Trailer may skid; steer gently.

  • Blind spots: Larger with trailer; use mirrors and camera systems. Always check before changing lanes or turning.

  • Fuel-efficient driving: Smooth acceleration, anticipate traffic, use momentum. Avoid excessive idling.

Safety, Load Securing and Passenger Safety

  • Load securing: Use approved lashings, straps with tensioners. Number of straps depends on load weight and friction. Minimum lashing capacity: 50% of load weight.

  • Passenger safety: Ensure all passengers wear seat belts if available. Standees only allowed in designated areas with handholds. Emergency exits must be unobstructed.

  • Trailer load: Must be secured and not exceed trailer's MAM. Check that load does not protrude dangerously; mark if protruding over 1 m at rear.

  • Fire safety: Bus must have fire extinguishers and first aid kit. Check expiry dates. Know location of emergency exits and how to operate them.

  • Passenger communication: In case of emergency, give clear instructions. Use PA system if available.

  • Safe coupling: Ensure trailer is properly hitched, safety cable attached, lights working, and brakes tested. Use wheel chocks when coupling.

  • Pre-trip inspection: Check tyres, lights, brakes, coupling, load securing, and emergency equipment.

  • Passenger comfort: Avoid harsh driving; ensure ventilation and temperature control.

Driving and Rest Time Rules, Tachograph and Professional Driver Responsibilities

  • EU rules: Maximum daily driving time 9 hours (extendable to 10 hours twice a week). Weekly driving max 56 hours; fortnightly max 90 hours.

  • Breaks: After 4.5 hours driving, take a 45-minute break (can be split into 15+30 minutes).

  • Daily rest: 11 hours (reducible to 9 hours three times between weekly rests). Weekly rest: 45 hours (reducible to 24 hours).

  • Tachograph: Must be used correctly; record all activities (driving, other work, availability, rest). Manual entries for non-driving days.

  • Driver card: Personal; must not be used by others. Report lost/stolen card immediately. Download data regularly (every 28 days for driver card, 90 days for vehicle unit).

  • Enforcement: Roadside checks; fines for infringements. Company responsible for compliance.

  • Professional driver responsibilities: Ensure vehicle roadworthy, comply with traffic laws, and complete training (e.g., CPC).

  • Record keeping: Keep tachograph records for at least one year; produce on request.

First Aid, Incident Management and Emergency Procedures

  • Scene safety: Park safely, turn on hazard lights, put on reflective vest, place warning triangle (if required). Call emergency number 112.

  • First aid: Check airway, breathing, circulation (ABC). Control bleeding with direct pressure. Do not move injured unless necessary.

  • Bus evacuation: Use emergency exits (doors, windows, roof hatches). Assist passengers; ensure no one left behind.

  • Fire: Use fire extinguisher if safe; aim at base of fire. Evacuate immediately if fire cannot be controlled.

  • Accident reporting: Exchange details with other parties; report to police if injury or significant damage. Complete accident report form.

  • Incident with trailer: Secure scene; check for leaks or hazards. Do not disconnect trailer unless necessary and safe.

  • Passenger care: Keep calm, provide reassurance, and administer first aid until help arrives.

  • Documentation: Record incident details, take photos if safe, and note witness information.

Vehicle Technology, Inspection and Maintenance of Bus and Trailer

  • Daily checks: Tyres (pressure, tread depth min 1.6 mm for cars, 1.0 mm for large vehicles? Actually for buses: 1.5 mm? Check: For vehicles over 3.5 t, min tread depth 1.0 mm. For trailers, same. For buses: 1.5 mm? I'll use: min tread depth 1.0 mm for large vehicles, 1.6 mm for cars.)

  • Brake system: Check air pressure (for air brakes), brake fluid level, and test brakes. Trailer brakes must engage when bus brakes applied.

  • Lights: Check all lights including indicators, brake lights, and trailer lights. Ensure reflectors are clean.

  • Coupling: Inspect hitch, safety cable, and electrical connection. Lubricate as needed.

  • Tyres: Check for damage, wear, and correct pressure. Twin tyres must be matched.

  • Periodic inspection: Bus must undergo annual roadworthiness test (syn) after 1 year, then annually. Trailer also requires inspection.

  • Maintenance: Follow manufacturer's service schedule. Keep records.

  • Defect reporting: Report any defects to operator; do not drive unsafe vehicle.

Environmental Driving, Fuel Efficiency and Noise

  • Eco-driving: Smooth acceleration and deceleration, use highest gear possible, anticipate traffic to avoid stop-start.

  • Idling: Turn off engine when stationary for more than 1 minute (except in traffic). Reduces fuel consumption and emissions.

  • Tyre pressure: Correct pressure reduces rolling resistance and fuel use. Check weekly.

  • Load: Remove unnecessary weight; roof racks increase drag.

  • Noise reduction: Avoid revving engine, use engine brake wisely, and keep vehicle maintained to reduce noise.

  • Route planning: Use GPS to avoid congestion and choose efficient routes.

  • Alternative fuels: Consider electric or hybrid buses; but for this exam, focus on efficient driving.

  • Fuel consumption: A bus with trailer consumes more fuel; plan for refuelling and use fuel-efficient techniques.
