Sign type	Warning Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	A side road joins from the left ahead but the central reservation (median) is continuous without a break. This means vehicles from the side road can only turn left into your nearside lane. There is no possibility of vehicles crossing from the opposite carriageway or making right turns at this junction. Maintain awareness for merging traffic from the left. If you intend to exit left onto the side road, signal early, check mirrors, and move to the left lane well in advance. This junction type is safer than junctions with central reserve breaks.

Typical location	Side Road on Dual Carriageway (No Central Reserve Break) signs appear on motorways and dual carriageways where minor roads join without median breaks allowing cross-traffic. Common on the M50 where distributor roads join, sections of the N11 and N7 with restricted access junctions, and dual carriageway bypasses around towns. The absence of a central reserve break means side road traffic can only turn left onto the dual carriageway and traffic on the dual carriageway can only exit left. No crossing movements or right turns are possible.

What This Means for Drivers

A side road joins from the left ahead but the central reservation (median) is continuous without a break.

This means vehicles from the side road can only turn left into your nearside lane.

There is no possibility of vehicles crossing from the opposite carriageway or making right turns at this junction.

Maintain awareness for merging traffic from the left.

If you intend to exit left onto the side road, signal early, check mirrors, and move to the left lane well in advance.

Penalties & Legal Consequences

Attempting to turn right onto a side road where no central reserve break exists requires crossing the median illegally, constituting dangerous driving: 5 penalty points, fines to €5,000, imprisonment, and disqualification for minimum 2 years.

Many dual carriageway medians have barriers making such violations physically impossible.

If merging traffic from the side road causes collision by failing to yield, primary liability falls on the merging driver.

Main carriageway drivers must still demonstrate defensive awareness—contributory negligence applies if avoidance was possible.
