- Intro
- What does an OPPOSING TRAFFIC HAS EXTENDED GREEN sign warn you?
- A three-digit interstate starts with an odd number, such as I-180. What is it usually?
- A DIVIDED HIGHWAY ENDS sign is ahead. What should you do?
- What does an ADDED LANE sign mean?
- Traffic is backed up across a railroad crossing. Where should you stop?
- Recap
In short
It is posted where opposing traffic may continue to move after your signal has turned red. When the first of three digits is odd, the highway is usually a spur connecting with another interstate at only one end. You will be on a road with two-way traffic; keep to the right of the centerline and watch for oncoming traffic.

Intro
Signs, signals and road markings talk to you in shapes and colors. Let's decode five of them from the Pennsylvania Driver's Manual. For each one, pick your answer before I reveal it.
Situation 1
You're waiting at a light, and a sign beside the signal reads OPPOSING TRAFFIC HAS EXTENDED GREEN. What does an OPPOSING TRAFFIC HAS EXTENDED GREEN sign warn you? The answer is A: Oncoming traffic may keep moving after your light turns red. It is posted where opposing traffic may continue to move after your signal has turned red. When your light turns red, don't assume oncoming cars are stopping. They may still have a green, so wait until they've actually stopped.
Situation 2
You're following signs for I-180. It's a three-digit interstate number, and the first digit is odd. A three-digit interstate starts with an odd number, such as I-180. What is it usually? The answer is C: A spur connecting to another interstate at one end. When the first of three digits is odd, the highway is usually a spur connecting with another interstate at only one end. Odd first digit, think one-ended: a spur that branches off and meets another interstate at only one end.
Situation 3
The median beside you is about to run out, and a DIVIDED HIGHWAY ENDS sign goes by. A DIVIDED HIGHWAY ENDS sign is ahead. What should you do? The answer is C: Keep right of the centerline and watch for oncoming traffic. You will be on a road with two-way traffic; keep to the right of the centerline and watch for oncoming traffic. Soon you'll share the road with oncoming traffic. Stay right of the centerline and keep watching for cars coming toward you.
Situation 4
You're on a highway near an on-ramp, and a yellow ADDED LANE sign shows the ramp traffic joining. What does an ADDED LANE sign mean? The answer is A: Entering traffic gets its own new lane, so merging is not necessary. It means merging is not necessary because the entering traffic uses a new lane added to the roadway. With an added lane, the entering traffic gets a brand-new lane of its own, so nobody has to merge.
Situation 5
Traffic ahead has stopped, and the line of cars stretches across a railroad crossing in front of you. Traffic is backed up across a railroad crossing. Where should you stop? The answer is A: Where your vehicle is entirely clear of the tracks. Do not stop on a railroad track. If traffic is backed up, stop where your vehicle will be entirely clear of the tracks. Never stop on the tracks. Wait behind the crossing until there's room for your whole car on the other side.
Recap
It is posted where opposing traffic may continue to move after your signal has turned red. When the first of three digits is odd, the highway is usually a spur connecting with another interstate at only one end. You will be on a road with two-way traffic; keep to the right of the centerline and watch for oncoming traffic. It means merging is not necessary because the entering traffic uses a new lane added to the roadway. Do not stop on a railroad track. Nice work.
