Theory Test Centres in Caernarfon, Gwynedd

Driving in and around Caernarfon

Preparing for your theory test in Caernarfon means understanding a mix of town, rural and coastal driving. The A487 runs along the eastern side of the town, linking Caernarfon with Bangor to the north-east and Porthmadog to the south. This route features varying speed limits, merging lanes and busy junctions, all of which relate directly to Highway Code rules on lane discipline, priority and safe following distances.

Within the town centre, around Caernarfon Castle, Pool Street and the one-way system near the harbour, you’ll encounter narrow streets, pedestrian crossings and frequent tourist traffic. Theory questions on zebra, pelican and puffin crossings, as well as dealing with vulnerable road users, are particularly relevant here, especially during the summer when visitors crowd the historic waterfront.

Local hazards and road types

To the east and south-east, the roads begin to climb towards Eryri (Snowdonia), where you’ll find winding rural routes with sharp bends, hidden dips and limited visibility. Routes towards Llanberis and Beddgelert can be exposed and require careful speed management, observation and use of appropriate gears on descents. These conditions tie in closely with theory topics on stopping distances, braking on downhill gradients and correct use of headlights in poor visibility.

Many local roads are single carriageways with farm entrances, slow-moving vehicles and occasional livestock. The Highway Code’s guidance on passing horses, cyclists and agricultural vehicles at safe speeds and distances is highly relevant when driving around Caernarfon’s outskirts and nearby villages.

Weather, coastal conditions and the Highway Code

Caernarfon’s coastal position on the Menai Strait means you should be prepared for strong crosswinds, sea mists and frequent rain. The A487 and roads running close to the water can become slippery, especially after prolonged wet weather. For the theory test, this links to questions on increased stopping distances in rain, the correct use of dipped headlights in poor visibility and safe separation distances at higher speeds.

In winter, frost and ice are more likely on rural routes leading into Eryri, particularly in shaded areas and on bridges. You should revise Highway Code advice on driving in wintry conditions, including gentle acceleration and braking, using higher gears to reduce wheelspin and planning extra time for journeys. Understanding how Caernarfon’s local geography affects real driving will help you answer scenario-based theory questions with greater confidence and context.
