Speed Limits, Right-of-Way, Stopping, Intersections, Turns, Turns on Red and Roundabouts

Speed limits
A posted limit is a reasonable speed for that road's design and expected traffic in dry, clear weather. In rain, fog, poor pavement or heavy traffic a reasonable speed may be slower than the sign. Whatever the sign says, Ohio law forbids driving faster than lets you stop within the assured clear distance ahead: you must be able to stop in the space you can see.
Typical limits by location (Ohio Revised Code 4511.21):
| Limit | Where |
|---|---|
| 15 mph | Alleys inside a municipality |
| 20 mph | School zones during recess and while children arrive or leave |
| 25 mph | Streets inside a municipality |
| 35 mph | State routes and through highways inside a municipality outside business districts (not controlled-access highways) |
| 50 mph | State routes inside a municipality outside urban districts |
| 55 mph | Freeways with paved shoulders inside a municipality |
| 70 mph | Rural freeways |
Right-of-way
Right-of-way is the priority to proceed. Yield to:
- the driver who arrives first at an intersection;
- oncoming traffic when you turn left;
- the driver on your right when you both reach a four-way intersection at the same time;
- traffic on a public road when you enter from a driveway or private road;
- traffic already on a freeway when you are on the entrance ramp;
- pedestrians, bicyclists and drivers still in the intersection;
- public safety vehicles (police, fire, ambulance);
- funeral processions.
Starting, moving and stopping
Start with your right foot on the brake and the selector in park, then turn the key or press Start. To move, select drive, check ahead, to the sides and behind, signal, and press the accelerator gently with the ball of your foot and heel on the floor. To stop, check the mirrors, move to the brake and press steadily. Stopping distance depends on your reaction time, your speed, the brakes and the pavement (wet, dry, icy, salted, gravel). Keep a 3 to 4 second gap behind the vehicle ahead.
You must stop:
- at the sidewalk (or before the roadway if there is none) when leaving an alley, driveway or private road in a business or residential district, yielding to pedestrians on the sidewalk;
- behind the stop line or crosswalk at any stop sign or red signal;
- behind the line or crosswalk before a turn on red, proceeding only after a full stop and yielding to all crossing traffic and pedestrians;
- before entering an intersection when there is no room on the far side for your vehicle, even on a green light;
- at a flashing red signal, yielding to traffic that need not stop;
- for an approaching public safety vehicle with flashing lights and siren, unless it is on the other side of a divided highway: pull as far right as possible and stay until it passes.
Steering and backing up
Steer the way you want the vehicle to go, forward or in reverse. Hold the wheel at the 4 and 8 o'clock positions with a firm but gentle grip, which keeps control and keeps your arms clear of a deploying air bag.
Before backing, walk around the vehicle: children and small objects are invisible from the seat. Foot on the brake, shift to reverse, left hand at 12 o'clock, right arm over the passenger seat, and look through the rear window; mirrors and back-up cameras help but do not show everything. Accelerate gently and stay slow, since the vehicle is harder to steer in reverse; steer slightly toward where the rear should go, glance front and sides if turning, and keep looking back until fully stopped.
Intersections and turns
At every intersection slow down and search for traffic controls, oncoming and cross traffic including motorcycles and bicycles (left, right, then left again), pedestrians, road conditions and limited-visibility spots.
Turning: signal at least 100 feet ahead with the indicator or a hand and arm signal; search all corners; get into the lane closest to the direction of the turn and hold it; look through the turn to the farthest point of your path; accelerate smoothly, cancel the signal and check behind.
Right turns: do not swing wide to the left first; turn from the rightmost part of your lane into the rightmost lane of the new street. Left turns: yield to oncoming traffic; turn from the leftmost part of your lane into the lane just right of the center line, on four-lane roads too. At a green light with no gap to turn left, wait; if traffic is heavy, position the nose slightly past the stop bar and turn as soon as it is safe, yielding to pedestrians and oncoming vehicles. On multi-lane turns, pick your lane and stay in it through the turn.
Right on red is allowed unless a sign prohibits it, after a complete stop and once all crossing traffic and pedestrians are clear. Left on red is allowed only from the extreme left lane of a one-way street onto another one-way street, unless posted otherwise.
Tips: when the light turns green, pause before entering; do not count on others obeying signals. If traffic is backed up across the intersection, wait before it rather than stopping inside it. Turning onto a road, make sure the gap is large enough to cross, enter the right lane and get up to speed. Do not pull out in front of a vehicle just because its turn signal is on; the driver may turn after passing you or may have forgotten the signal. At a stop sign where you cannot see, edge forward to check before entering.
Roundabouts
A roundabout is a circular intersection where traffic moves counterclockwise around a raised center island and entering traffic yields to circulating traffic. Check the signs for your lane on the approach, since you cannot change lanes inside; slow down; look left and enter when clear; keep moving without stopping or changing lanes; signal and take your exit: 1st exit to turn right, 2nd to go straight, 3rd to turn left, 4th to make a U-turn.
