Diverted Traffic (Straight)

Diverted Traffic (Straight) signs are commonly placed at junctions throughout Ireland where the official detour route continues straight ahead rather than turning.

You'll frequently see these signs at crossroads in rural areas when main routes like the N17 Galway-Sligo road require diversions, ensuring drivers don't mistakenly turn off the detour path.

They're particularly common at roundabouts in towns like Athlone or Mullingar when the N4 or N6 routes need temporary closure, directing diverted traffic straight through rather than exiting.

These signs also appear at T-junctions near major cities like Cork and Dublin where multiple road options could confuse drivers following emergency diversions around incidents or planned maintenance works.

This sign instructs all traffic following an official detour route to continue straight ahead at the approaching junction, rather than turning left or right.

It confirms that the designated diversion path proceeds directly through the intersection without deviation.

The sign prevents drivers from inadvertently leaving the approved detour route by taking side roads that might appear to offer shortcuts.

It maintains the integrity of the planned traffic flow around the closure or roadworks, ensuring that diverted vehicles follow the route that has been assessed for safety and capacity.

The straight-ahead direction keeps traffic moving efficiently toward the point where they can rejoin their original intended route.

While continuing straight ahead when directed may seem straightforward, failure to comply with detour signage is an offense under Irish traffic legislation.

Ignoring the straight-ahead instruction and turning off the official detour route can result in fixed penalty notices of €80 for non-compliance with traffic management orders.

If drivers leave the designated detour and subsequently access restricted or closed roads, fines can escalate to €2,000 with 2 penalty points for careless driving.

More serious consequences arise if unauthorized route deviations lead to interference with emergency services or construction work, potentially resulting in dangerous driving charges with penalties up to €5,000, imprisonment, and driving disqualification.

Local authorities often monitor detour compliance at key decision points.

Understanding detour continuation signs is part of the Irish driving theory test's temporary traffic management section.

You need to know that 'straight ahead' instructions for diverted traffic are mandatory, not suggestions.

Theory test scenarios may present complex junction situations where you must identify the correct path when following an official diversion.

The test emphasizes that detour signs take precedence over normal road markings or your intended destination.

During practical driving tests, compliance with detour straight-ahead instructions demonstrates your ability to follow sequential signage, maintain route discipline, and resist the temptation to take seemingly more direct alternatives.

Examiners assess whether you can distinguish between normal navigation choices and mandatory detour compliance.
