Comply with Traffic Rules, Regulations and Road Safety Requirements
What this domain tests
Compliance with Philippine traffic law and defensive driving standards as they apply to a heavy articulated vehicle: RA 4136 and its IRR, LTO licensing and registration, signs and signals, speed and following distance, load and dimension limits, and the special rules on seatbelts (RA 8750), distracted driving (RA 10913) and drunk driving (RA 10586).
Core rules
- Obey the signal, then the sign, then the road marking, then the rule of right of way - never the other driver's goodwill.
- Overtake only where the centre line permits and the whole combination can complete the pass; a loaded rig needs far more road than a car.
- Keep a time gap, not a car-length gap. Three seconds is the dry-road minimum for a light vehicle; a loaded articulated vehicle needs five to six seconds, and more in rain or darkness.
- Know your limits: GVW, axle loads, height, width and length. A low bridge or truck-ban street is a legal limit, not a suggestion.
- Carry and present OR/CR, licence, insurance and trip documents; secure cargo and place the early warning device when stopped on the road.
Worked example
At 60 km/h, 60 ÷ 3.6 = 16.7 m/s. A three-second gap is 50 m; a loaded rig at five seconds is 83 m, and in rain at six seconds is 100 m. Reasoning: braking distance rises with mass and low friction, so the gap must grow even though the speed limit has not changed. The sign says 60; the safe speed may be 40.
Traps
- Treating the speed limit as a target.
- Overtaking on a solid line because the road 'looks clear'.
- Ignoring a 'no truck' or load-limit sign on a shortcut.
- Tailgating to stop cars cutting in.
- Rolling through a stop line or a railway crossing.
