T Junction (Major Road) Ahead

This warning appears where minor roads terminate at major priority routes, particularly common throughout rural Ireland where local roads (L-class), regional roads (R-class), or minor N-roads meet busy N-roads or major regional routes.

Typical locations include agricultural areas in Cork, Tipperary, Limerick, and Galway where farm access roads and village connectors join primary routes.

You'll encounter these on approaches to N7, N8, N20, N24, and other busy N-roads where traffic volumes and speeds create significant hazards for vehicles emerging from minor roads.

Sign placement occurs 100-200 metres before the T-junction, often accompanied by YIELD or STOP signs at the junction itself.

These warnings are particularly important where approach curves, hedgerows, or terrain prevent early junction visibility, or where recent traffic speed increases on main roads made advance warnings necessary.

This sign warns of approaching T-junction termination at a major road where you will not have priority—you must yield or stop (depending on junction control) to allow main road traffic to pass.

The T-configuration means you can turn left or right but cannot continue straight—your road ends.

The warning emphasizes that the cross-road is a major priority route with higher traffic volumes and speeds, requiring particular caution.

Drivers should reduce speed upon seeing this warning, assess which direction they'll turn, and prepare for potentially long waits if main road traffic is heavy.

The major road designation indicates traffic flows at or near speed limits (often 80-100km/h), making gap judgment critical.

Some T-junctions have STOP sign control (mandatory halt), others have YIELD signs (stop only if necessary).

The advance warning allows time to position correctly, check mirrors, signal intentions, and prepare for the turning maneuver.

The advance warning sign itself carries no penalty, but failing to yield or stop appropriately at T-junctions with major roads frequently results in serious collisions and charges.

Emerging from minor roads without yielding properly constitutes careless driving at minimum (€80-€120, 2-3 penalty points), escalating to dangerous driving (€5,000, 5 penalty points, disqualification) if collisions occur, especially those involving high-speed main road traffic. 'Failed to yield' collisions at T-junctions typically establish primary liability (80-100%) against the emerging driver.

Insurance companies examine whether drivers from minor roads took adequate precautions—the advance warning establishes drivers had notice to prepare.

Fatal accidents at such junctions can result in vehicular manslaughter charges under Section 4 of the Road Traffic Act 2010, carrying prison sentences up to 10 years.

The RSA identifies T-junctions as high-risk locations accounting for significant collision percentages.

Theory test questions about T-junctions at major roads emphasize priority rules, appropriate responses to warnings, and safe gap judgment.

Questions assess understanding of what this sign means, who has priority, and what preparations you should make when seeing it.

Scenario questions might test understanding of differences between YIELD vs STOP control at such junctions.

Practical driving tests always include junctions where minor roads meet major roads; examiners assess appropriate responses to advance warnings: early speed reduction, correct lane positioning for intended turn, timely signaling, effective observation assessing main road traffic speeds and gaps, and safe junction execution.

Common faults include inadequate observation (underestimating main road traffic speeds), poor gap judgment (pulling out when insufficient space exists), or approaching junctions too fast indicating failure to respond to advance warnings.
