At a T-intersection, the right of way belongs to drivers on the through road—the continuous road that keeps going. If you’re on the road that dead-ends into it, you’re on the stem of the T, and you must yield to every vehicle already traveling on the through road before you pull out. Signs, signals, and a few specific situations can shift that rule, but the default puts the burden on the driver entering from the terminating road.
When There Are No Signs or Signals
An uncontrolled T-intersection has no stop sign, no yield sign, and no traffic light. The rule there is simple: through-road traffic keeps moving, and the stem driver waits. Treat the through road the way you’d treat a highway on-ramp. The drivers already on it aren’t expected to slow down or make space for you.
This comes from a broader principle in the Uniform Vehicle Code, which most states have adopted in some form. At an intersection without controls, a driver approaching must yield to any vehicle already in it, and when two vehicles arrive at roughly the same moment from different roads, the driver on the left yields to the driver on the right.1Federal Highway Administration. 2009 Edition Chapter 2B Regulatory Signs, Barricades, and Gates – Section: 2B.04 Right-of-Way at Intersections At a T, the left-right tiebreaker rarely decides anything in practice. The stem driver yields regardless of position because the through-road driver is already on the dominant road.
Uncontrolled Ts show up most often on quiet residential streets and rural roads. No sign doesn’t mean no rule. If a stem driver pulls into through traffic and a collision follows, the blame lands on the stem driver.
When a Stop or Yield Sign Is Posted
Posted signs override the default and spell out who waits.
Stop Signs
A stop sign requires a full stop before the stop line, crosswalk, or edge of the intersection, whichever you reach first. After stopping, you yield to every vehicle on the through road and every pedestrian in or approaching a crosswalk before you proceed.2Federal Highway Administration. 2009 Edition Chapter 2B Regulatory Signs, Barricades, and Gates – Section: 2B.05 STOP Sign Most signed T-intersections put the stop sign only on the stem approach, which just reinforces the default rule with an enforceable sign.
Yield Signs
A yield sign doesn’t require a full stop. It tells you to slow down and give way to traffic with priority, stopping only if you need to in order to avoid a conflict. The Federal Highway Administration describes a yield sign as assigning right of way to traffic on certain approaches and requiring the controlled driver to slow to a reasonable speed or stop when necessary.3Federal Highway Administration. 2009 Edition Chapter 2B Regulatory Signs, Barricades, and Gates – Section: 2B.08 YIELD Sign You’ll see yield signs on the stem of a T where visibility is good and traffic is light enough that a full stop would usually be unnecessary.
When There’s a Traffic Light
If a T-intersection has a signal, the signal controls everything. A green light means you may proceed, but a driver turning left on a solid green still has to yield to oncoming through traffic unless a green arrow gives a protected turn. This catches people off guard at Ts. The left-turning driver on the through road may assume they have the go-ahead and forget that oncoming traffic has the same green.
Every state allows a right turn on red after a full stop and yielding to all traffic and pedestrians, unless a “No Turn on Red” sign prohibits it at that intersection. A handful of cities have restricted the practice more broadly to protect pedestrians.
A left turn on red is far more limited. Most states that allow it restrict it to turning from one one-way street onto another one-way street. Running a red light carries steep fines and typically adds points to your driving record, and adjusters and officers treat it as strong evidence of fault if a crash follows.
Pedestrians and Cyclists
Pedestrians have right-of-way protection at a T-intersection even when there’s no painted crosswalk. In nearly every state, an unmarked crosswalk is understood to exist wherever the edges of a sidewalk or walkway would logically extend across the intersection. Drivers must yield to a pedestrian in or approaching that area, and when one vehicle stops for a pedestrian, drivers in adjacent lanes must stop too rather than pass the stopped car.
Cyclists follow the same right-of-way rules as motor vehicles. The National Highway Traffic Safety Administration notes that bicyclists have the same rights as drivers on the road.4NHTSA. Share the Road: Its Everyones Responsibility A cyclist on the through road of a T has the same priority as a car in that position, and a stem driver must yield. Cyclists are harder to spot, which is why checking carefully before pulling out matters.
Driveways, Alleys, and Private Roads
The same logic reaches beyond public T-intersections. If you’re pulling out of a driveway, alley, parking lot, or private road, you yield to every vehicle and pedestrian on the public road you’re entering, whether or not a sign is posted. You also have to stop before crossing any sidewalk and yield to pedestrians on it. Drivers on the public road aren’t required to slow down for you or anticipate that you’ll pull out. The law puts the full burden on the person entering traffic.
When the Through-Road Driver Loses Priority
Right of way isn’t a license to drive however you want. Several situations strip it away or at least split the blame.
Speeding
Many states have an explicit rule that a driver traveling at an unlawful speed forfeits any right of way they would otherwise have. A driver doing 50 in a 30 zone on the through road can’t simply point to the dominant road after a crash. The forfeiture doesn’t hand the right of way to the other driver, though. It leaves neither driver with legal priority, and both can be found at fault.
Emergency Vehicles
When an emergency vehicle approaches with lights and sirens on, every other driver’s right of way disappears. You pull to the right and stop, regardless of what road you’re on, whether you have a green light, and whether you’re on the through road at a T. Blocking an emergency vehicle is illegal, and the fines are typically far higher than for ordinary traffic violations.
Failure to Use Due Care
Even with right of way, you have a duty to drive with reasonable care. A through-road driver who sees another car pulling out and makes no effort to brake, swerve, or honk can share liability in a crash. Some states apply the “last clear chance” doctrine here. The point is that right of way isn’t an absolute shield.
Fault and Insurance After a T-Intersection Crash
After a collision at a T, insurers and officers start from a simple presumption: the driver on the terminating road failed to yield and is at fault. The stem driver carries the burden of showing something else went wrong, such as a malfunctioning signal, an obstructed sight line, or a speeding through-road driver.
That presumption isn’t the end of the analysis. Most states use some form of comparative negligence, so fault can be split between both drivers as a percentage. If you had the right of way but were distracted or speeding, your compensation in a lawsuit gets reduced by your share. In roughly a dozen states that follow a stricter rule, being 50 or 51 percent at fault bars you from recovering anything at all. The details vary by state, but the principle is the same everywhere. Right of way gives you priority at the intersection. It doesn’t give you immunity from the consequences of driving carelessly while using it.
