Signaling when going straight at a roundabout depends on local driving rules, but standard UK Highway Code guidelines (widely referenced in driving resources) emphasize safety and clarity for other road users.

Core UK Rule

In the UK, do not signal when approaching a roundabout if going straight ahead (typically the 2nd or 3rd exit, around the 12 o'clock position). Select the left-hand lane (or any straight-ahead marked lane). Once past the exit before yours, signal left to indicate you're exiting. This tells waiting drivers it's safe to enter.

Why No Approach Signal?

Not signaling on approach signals "straight ahead" to others—signaling left might confuse drivers into thinking you're taking the first exit, while right implies a full circuit. Driving instructor videos stress this avoids hazards, especially at multi-exit roundabouts. As one expert notes: "Not signaling means I'm going ahead, but you always signal left to leave a roundabout."

Step-by-Step Process

Follow these steps for a typical 4-exit roundabout (exits numbered clockwise from your approach):

  1. Approach in the left lane without signaling.
  2. Yield to traffic already circulating.
  3. Enter without signaling.
  4. After passing the exit before yours (e.g., after exit 1 for exit 2), signal left.
  5. Exit smoothly while signaling left.

Regional Variations

Rules differ globally—here's a quick comparison from forum discussions and guides:

Region| Approach Signal?| Exit Signal?| Key Note 245
---|---|---|---
UK| None| Left after prior exit| Left lane; clock-face method.
NZ/Aus| None if < halfway; Right if > halfway| Left to exit| Lane discipline crucial.
US (some states)| Left on entry for straight| Left to exit| Follow markings strictly.

TL;DR: For UK-style roundabouts, no signal approaching straight ahead—signal left only to exit after the prior junction. Practice with diagrams boosts confidence.
