Confusion on Sukhumvit: Right Turn from the Middle Lane?
A traffic sign on Sukhumvit Road heading toward Thong Lo (Soi 55) is stirring heated debate online. The key question: Can drivers stop in the middle lane at a red arrow to make a right turn? The answer surprises many motorists.
Three Lanes, Three Rules
The sign gives clear instructions—or so it seems. The right lane is for right turns only, the left lane for straight-ahead traffic, and the middle lane shows both arrows: straight and right.
“This confuses me every morning on my way to work,” one user wrote on Twitter.
The Official Answer: Yes
Police confirm that waiting in the middle lane is allowed—even if the straight-ahead light is green.
“As long as the right-turn arrow is red, you are permitted to wait in your lane,” a police spokesman explained. The solid white stop lines before the intersection make it clear: stay in your lane.
From Dashed to Solid Lines
The lane markings hold the key. Before the intersection, the lines are dashed—drivers may still change lanes. But as the light approaches, the markings turn solid, meaning:
-
No lane changes
-
No overtaking
-
Strictly follow the lane’s direction
“Many drivers make the mistake of switching lanes at the last second,” warned a traffic expert. “That’s not only illegal but extremely dangerous.”
A Symptom of Bangkok’s Traffic Woes
The debate highlights a broader issue: Bangkok’s overloaded roads and often confusing signage. The city is working on improvements, including clearer signs, digital traffic lights, and campaigns to boost public transport.
Until then, one veteran taxi driver offered advice: “Better to look twice than risk an accident.”
So next time you’re on Sukhumvit heading for Thong Lo—yes, the middle lane is fine for waiting. Just bring patience. In Bangkok traffic, you’ll need it anyway.
