Sri Lanka Driving Licence Written Exam — Free Practice Test

There is no floating-point arithmetic in this tool. Correctness comes from two places: a question bank where every answer is transcribed from a cited rule rather than written from memory, and a scorer that applies the Department's published pass mark exactly.

Where the questions come from

Sri Lankan road signs are prescribed under the Motor Traffic Act (Chapter 203) and detailed in the Road Development Authority's Manual on Traffic Control Devices. The scheme is the one you see on the road: a warning is an amber diamond with a black border and a black symbol; a prohibition is a white circle inside a red ring, with a red diagonal bar where the action is forbidden; a mandatory instruction is a solid blue circle with a white symbol; information and direction signs are rectangles, blue on ordinary roads and green on expressways. A question may only assert a meaning that appears in one of those documents, the Highway Code, or a gazetted schedule. Anything that could not be sourced was dropped from the bank rather than guessed — which is why this page will not tell you how many days you must wait before a re-sit.

Where a question quotes a number, that number is imported from the module that already owns it. The national speed limits come from the same table as the speed limit finder, and the spot fines from the same schedule as the traffic fine calculator. A validation pass asserts the two still agree, so a gazette amendment shows up as a failed check instead of a stale answer.

How a paper is drawn

A paper is stratified, not sampled at random from the whole bank. Questions available for your licence class are pooled, then each topic is given a fixed share of the paper: 20% warning signs, 20% prohibitory & mandatory signs, 10% informatory & direction signs, 15% road markings & traffic lights, 15% police signals & right of way, 20% rules, documents & penalties. Fractional seats are resolved by largest-remainder rounding, ties broken by syllabus order — so a 10-question set splits 2 / 2 / 1 / 2 / 1 / 2 rather than landing on ten sign questions in a row. If a topic cannot fill its seats for your class, they go back to the other topics instead of shortening the paper. Question order and option order are both shuffled by a seeded generator, and the seed is printed on the result card so the identical paper can be rebuilt or shared.

How it is scored

Scoring follows the Department's electronic test: unanswered questions count as wrong, and there is no negative marking. The pass threshold is required = ceil(total × 75 / 100), and you pass when your correct count is at least that — 30 of 40, or 15 of 20, or 8 of 10. The same number is derived a second way in the code, by counting upwards until the percentage reaches the pass mark, and the two are cross-checked against each other for every paper length from 0 to 120. That check exists for one reason: the boundary. Exactly 30 of 40 is 75.0% and passes; one fewer is 72.5% and fails.

Each topic is then scored on its own: 85% or better is Strong, 60–84% is Revise, and below 60% is Weak. The weak topics feed the “practise weak topics” button, which builds a short untimed set from exactly those. A full 40-question mock is timed at 60 minutes, with shorter papers scaled in the same proportion (30 minutes for 20, 15 for 10).

Every figure below was worked out by hand first, then checked against the code. The self-check runs on each page load, and the badge on the calculator turns if it ever disagrees.

37 signs shown. Shapes and colours follow the RDA Manual on Traffic Control Devices; a posted sign always overrides a national default.
