The LTO (Land Transportation Office) Exam is the written examination required to obtain a Philippine driver's license — whether a Student Permit, Non-Professional License, or Professional License. This complete reviewer guide covers all the topics tested on the LTO written exam: traffic laws, road signs, safe driving practices, and vehicle regulations. Use this guide alongside practice tests to pass your LTO exam on the first attempt.
The LTO (Land Transportation Office) written examination is the standardized test administered by the Philippine government's Land Transportation Office to all applicants for a driver's license. The exam is a required step in the licensing process — you must pass the written test before proceeding to the practical driving examination and medical clearance.

Practice with our lto exam reviewer covering the full range of official LTO exam topics and road signs.
The LTO written exam draws questions from three primary content areas:
1. Road Signs (Panatagan sa Daan):
Philippine road signs are classified into three categories: Regulatory Signs (white background — must be obeyed, e.g., speed limits, no entry, no U-turn), Warning Signs (yellow background — warn of hazards ahead, e.g., curve ahead, pedestrian crossing), and Informational/Guide Signs (green or blue background — provide directions, distances, and service information). Knowing the color-coding and specific meanings of common signs is essential — road sign questions account for a large portion of the LTO exam.
2. Traffic Laws and Regulations (Republic Act 4136):
Republic Act 4136, the Land Transportation and Traffic Code, governs all Philippine road users. Key topics include: speed limits (60 kph on national roads, lower in school zones and residential areas), right-of-way rules, overtaking procedures, proper use of lanes, use of headlights, and penalties for traffic violations. The Anti-Drunk and Drugged Driving Act (RA 10586) and the Seat Belt Law (RA 8750) are also tested.
3. Safe and Defensive Driving:
Questions cover defensive driving principles, proper vehicle handling in hazardous conditions (rain, fog, night driving), correct following distances, proper lane changing procedures, how to handle skids, and road etiquette. The LTO exam also tests knowledge of what to do at the scene of an accident.
For comprehensive practice, use our lto exam reviewer covering all three content areas with official-format questions and answers.
Based on the official LTO question bank, these topics are most frequently answered incorrectly:
Speed limits in special zones: The national road speed limit is 60 kph, but school zones (20 kph), hospital zones, and residential streets have lower limits. Many candidates default to 60 kph incorrectly for all road types.
Right of way at uncontrolled intersections: At an intersection without traffic signs or signals, the driver on the right has the right of way. At T-intersections, through traffic has right of way over vehicles entering from the minor road.
Road sign color meanings: White background = regulatory (must obey); Yellow = warning (caution required); Green = informational/directional. Mixing up warning and regulatory signs is a common error.
Following distance: The standard safe following distance is at least 2 seconds behind the vehicle ahead (at normal speeds) — increase to 4+ seconds in rain or low visibility. Some candidates confuse following distance rules with speed limits.
Overtaking rules: You may not overtake on hills, curves, bridges, tunnels, intersections, or where a solid yellow center line is present. Practice all these categories with our lto exam reviewer questions.
