Master all Philippines LTO road signs for your 2026 exam. Regulatory, warning, informational & special signs with the top 10 most-tested signs.
Why Road Signs Are Critical for the LTO Exam
The LTO theoretical exam — also called the LTO written exam — is a 40-item multiple-choice test that applicants for a Student Permit or a Non-Professional or Professional Driver's License must pass. A score of 30 out of 40 (75%) is required to pass. Road signs questions consistently account for 10 to 15 items — roughly one-quarter to one-third of the entire exam — making them the single largest topic block tested.
The LTO bases its sign questions on the official Philippine sign standards published by the DPWH and adopted nationally under Republic Act 4136, the Land Transportation and Traffic Code. Signs follow international conventions (Vienna Convention on Road Signs and Signals) adapted for Philippine road conditions, including MMDA-specific signs used in Metro Manila. Understanding the color, shape, and symbol system behind Philippine road signs is the fastest path to mastering this section.
How Many Sign Questions Appear on the LTO Exam?
- Student Permit exam: Approximately 10–12 road sign questions out of 40 items
- Non-Professional License exam: Approximately 12–15 road sign questions, including sign identification by shape and color
- Professional License exam: Approximately 12–15 road sign questions plus traffic control device questions
Questions typically show a sign image or describe a sign's color/shape and ask what it means, or describe a situation and ask which sign applies. The exam is administered via computer terminal at LTO offices using the LTMS (Land Transportation Management System) portal. Prepare with our dedicated LTO theoretical exam reviewer for full exam simulations.
Red-bordered or red signs that state mandatory rules drivers must follow. Ignoring them is a traffic violation under RA 4136. Examples: Stop, Yield, Speed Limit, No Entry, No U-Turn, No Parking, One Way.
Yellow diamond-shaped signs that alert drivers to hazards, changes in road conditions, or unexpected situations ahead. They do not prohibit — they advise caution. Examples: Curve Ahead, Slippery Road, School Zone, Railroad Crossing, Road Narrows.
Signs that give drivers useful information about routes, destinations, services, and facilities. They guide rather than restrict. Examples: Direction signs, Distance markers, Hospital signs, Gas Station ahead, Tourist destination signs.
Signs used in specific locations or situations such as school zones, construction zones, and MMDA-controlled intersections. Include variable message signs, temporary traffic control signs, and electronic road signs on EDSA and major highways.
