LTO Exam Coverage: RA 4136 Topics You Must Know

RA 4136: the foundation law

RA 4136, the Land Transportation and Traffic Code, is the base law behind most of what the LTO written exam tests: right-of-way rules, overtaking restrictions, speed limits, and the authority of road signs and traffic enforcers. One detail examinees often miss is that a traffic enforcer’s hand signal overrides the traffic light itself — if an enforcer signals stop on a green light, you stop.

Though RA 4136 dates back decades, it remains the active legal foundation for Philippine traffic law today. Newer acts amend or add to it rather than replace it, which is why LTO exam items still cite it directly even when the specific rule being tested comes from a later amendment.

Right-of-way and overtaking

This is the largest single topic block on the exam. Core rules include yielding to the vehicle approaching from your right at an uncontrolled intersection, yielding to traffic already circulating in a rotunda, and never overtaking at intersections, railway crossings, blind curves, hill crests, or on narrow bridges — all places where you can’t see far enough ahead to pass safely.

The same block also covers what to do when you can’t rely on signal lights. Standard hand signals exist for exactly this — left arm out straight for a left turn, bent upward at the elbow for a right turn, and pointed down for slowing or stopping — and they’re tested on the written exam even though most drivers rarely need to use them in a modern vehicle.

Speed limits

RA 4136 sets a graduated speed table for cars: 80 km/h on open country roads with no blind corners, 40 km/h on through streets or boulevards, 30 km/h on city and municipal streets with light traffic, and 20 km/h through crowded streets or near intersections. Trucks and buses are held to lower limits than cars on the same roads. Separately, Philippine expressways carry their own rules: a 100 km/h maximum and a 60 km/h minimum for cars, so driving too slowly on an expressway is also a violation.

On top of every posted number, RA 4136 also expects you to drive at whatever speed is safe and prudent for the actual road, traffic and weather conditions — even when that’s below the posted limit. A speed that’s technically legal on a dry day can still be a violation in heavy rain.

Driving under the influence

RA 10586, the Anti-Drunk and Drugged Driving Act, sets different blood alcohol concentration thresholds depending on the driver: below 0.05% for private non-professional drivers, but a strict 0.0% for professional drivers of trucks, buses and public utility vehicles, and for motorcycle riders. The law also covers driving under dangerous drugs, not only alcohol, and gives officers the authority to conduct field sobriety tests before a breath analyzer.

Refusing the mandatory testing carries its own separate consequence: your license can be confiscated and revoked for refusal alone, independent of whatever a test might have shown.

Distracted driving and seatbelts

RA 10913, the Anti-Distracted Driving Act, bans handheld calls and texting while driving — including while temporarily stopped at a red light or in traffic — with hands-free use allowed only if the device doesn’t block your line of sight. RA 8750, the Seat Belts Use Act, requires the driver and all front-seat passengers to buckle up on every trip, and bans children six years old and below from sitting in the front seat of a moving vehicle at all.

Beyond RA 4136: what else shows up on the exam

A handful of exam items sit outside RA 4136 entirely but are still fair game: RA 10930 governs license validity and the driver’s education requirements for new applicants, and practical rules like early warning device placement (at least 4 meters front and rear if you break down) and Metro Manila’s number coding scheme (UVVRP) also appear.

A few more practical items round out the exam beyond pure legal text: knowing not to restart an engine that has stalled in deep floodwater, recognizing that only time — not coffee or a cold shower — actually sobers up a drinking driver, and understanding that your license must be carried and shown to authorities on lawful demand any time you’re driving, not just kept safely at home. None of these replace RA 4136 as the exam’s backbone, but skipping them leaves easy points on the table.
