Your first merge onto I-270

I-270 circles Columbus, which makes it the freeway most of our students drive first: whatever suburb you live in, a ramp is close, and the next exit is never far. It is also where new drivers are most nervous, because everything happens at freeway speed.

The Ohio Driver Manual covers merging in one paragraph. A first drive needs a little more planning than that.

Pick the hour and the ramp

Go when the road is quiet: a weekend morning or the middle of a weekday. Choose a ramp with a long, straight acceleration lane and a stretch of freeway after it with no exit for a mile or two, so the first merge is the only hard thing.

Drive the plan as a passenger first, if you can. A learner who has seen the ramp once is a calmer driver on it.

The acceleration lane is for accelerating

The manual's instruction: on entering a freeway, be aware of the vehicle ahead, look over your shoulder in the direction you are merging and use your outside mirrors to find a gap, then signal and use the acceleration lane to reach the speed of traffic and merge with the flow. Then cancel the signal.

The common mistake is to creep down the ramp and arrive at the freeway at 40 mph, looking for a gap that fits a slow car. The gap fits a car at traffic speed. Press the gas on the ramp, match the speed you see, and the merge gets easier, not harder.

Watch the car ahead of you on the ramp. If it hesitates, you leave room; two cars merging into one gap is how ramps go wrong.

Find the gap and commit

Pick a gap early, aim for the space behind one car, and do not keep changing your mind. Mirror, signal, shoulder check, steer in smoothly, cancel the signal. Traffic already on the freeway cannot read your mind; a steady car with a signal on is easy to let in.

If the gap closes, slow a little and take the next one. The acceleration lane is long for a reason. What you do not do is stop at the end of it.

On the freeway: right lane and four seconds

The manual's lane rule for a road with four or more lanes is to drive in the right lane and use the lane just right of center to pass. For a first drive, stay right and let the world go by. Keep a three-to-four-second following distance; at freeway speed that is a longer gap than most new drivers leave, so count it off a sign or a shadow (manual, section 5).

Look far ahead, at the brake lights three and four cars up, not at the bumper in front. Freeway surprises come from a long way off if you are looking for them.

Know the Move Over law before you need it. Ohio requires every driver approaching a stopped police car, emergency vehicle, tow truck, snowplow, road maintenance or utility vehicle with its warning lights on to slow down and move into a lane not next to it, or, when a lane change is unsafe, to slow down and pass with caution (manual, section 9). You will meet one sooner or later.

Getting off

Plan the exit before you reach it: move to the lane nearest the exit early, so there is no quick lane change at the sign. Keep your speed while you are still on the main roadway, signal, move into the deceleration lane, and slow there. Check the posted speed for the ramp; many Columbus ramps bend hard.

If you miss the exit, take the next one. Never use the opening in the median; the manual reserves it for emergency and public safety vehicles.

The loop drive

Because I-270 is a loop, a good first drive is one or two exits in each direction: merge, settle in the right lane, exit, turn around on surface streets, and merge back the other way. Four merges in half an hour, each one a little calmer.

If you learned to drive somewhere without freeways, this is the drive to try with an instructor first: our driving lessons cover the roads around Columbus a student actually drives, and the road test guide covers the test, which scores the same lane and following-distance habits.

New to Ohio with a license from another state or country? The moving here guide covers the paperwork, and the Limited Term course is the Class D course the Ohio Traffic Safety Office names for non-renewable, non-transferable license applicants.
