Speed limit questions are among the most straightforward on the theory test, but they still catch people out. Whether you’re driving through Louth’s built-up areas at 50 km/h or on national roads at 100 km/h, knowing the limits is non-negotiable.
As Ireland’s smallest county, Louth packs two significant towns (Dundalk and Drogheda) into a compact area. The M1 motorway connects both to Dublin and Belfast, meaning heavy cross-border traffic. Drogheda’s steep hills and narrow bridge crossings are challenging. The coast road through Carlingford has scenic but demanding mountain sections. Cross-border driving rules (km/h vs mph speed limits) appear in theory tests.
Speed limit questions are pure memorisation — there’s no logic to derive, you either know the number or you don’t. The good news is there are only a handful of speed limits to learn.
The key numbers: Built-up areas: 50 km/h. Regional roads: 80 km/h. National roads: 100 km/h. Motorways: 120 km/h. Special zones (schools, housing estates) may have 30 km/h limits. Learner drivers have no separate speed limits but must display L plates.
Study approach: Create a simple table of all speed limits and review it daily. The questions will test you on specific scenarios (“what is the speed limit on a regional road?”) rather than asking you to recall the full table.
Common trap: The default speed limit when entering a built-up area is 50 km/h even without a sign — the built-up area boundary sign itself implies 50.

Louth has two test centres: Dundalk (9 weeks) and Drogheda (10 weeks).
Both are good options. Dundalk has a slightly shorter wait. Drogheda has steep hill starts on some routes.
The RSA question bank contains 60 speed limits questions. On any given test, you’ll typically see 3–12 questions from this category depending on the random selection.
