Light rail — Colorado Permit Test
Light rail on the Colorado permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Light Rail Vehicles are governed by all traffic signals and signs and have the same rights and responsibilities as other motorists when operating on the streets.
A light rail vehicle is traffic, not a train on a separate right of way. It obeys the same signals you do and gets the same treatment.
The LRVs are governed by all traffic signals and signs and have the same rights and responsibilities as other motorists when operating on the streets
In some areas Light Rail Vehicles operate on streets in the same direction as other motor vehicles, and in other areas they operate in the opposite direction from other traffic.
A vehicle coming the wrong way up the street is exactly what a driver is not looking for. Knowing it happens is the whole warning.
In some areas, LRVs will operate on streets in the same direction as other motor vehicles. In other areas, LRVs will operate in the opposite direction from other traffic
Each light rail car weighs up to 40 tons and cannot stop quickly, so never turn in front of an approaching Light Rail Vehicle.
Forty tons on steel rails has less grip and far more weight than any truck. It cannot swerve and it cannot stop for a car.

Never turn across a set of light rail tracks without checking in all directions, and watch for people getting on and off a stopped Light Rail Vehicle.
A second vehicle can be coming the other way on the next set of tracks, and passengers step off into the street.

Be especially alert in light rail areas because nearby buildings and foliage can make it difficult for motorists to see Light Rail Vehicles.
In a street the vehicle appears from behind whatever is at the corner. It is quiet and it is long, and both work against you.

Some light rail crossings have regular traffic lights, some have warning lights and some have gates with railroad type arms, and all of these signals mean stop and do not cross the tracks.
Three different pieces of equipment carry one message. A driver who reads them as different things will eventually get one wrong.
All these signals mean the same thing
Never drive around traffic gates at a light rail crossing, even if a Light Rail Vehicle has just passed, because another vehicle might be coming from the other direction.
The gate stays down because the crossing is not clear. The vehicle that just went by is often the reason you did not see the next one.

Be aware of your vehicle height near light rail, because overhead wires are a standard height of 18 feet, 6 inches above the center of the tracks, and you should always assume a hanging wire is electrified.
The wire carries enough power to kill through anything it touches. Assuming it is live costs nothing and assuming otherwise costs everything.

On the test
How are light rail vehicles treated on the street?
The same as other motorists, obeying signals and signs. A light rail vehicle is traffic, not a train on a separate right of way. It obeys the same signals you do and gets the same treatment. Colorado Driver Handbook, p.21: “The LRVs are governed by all traffic signals and signs and have the same rights and responsibilities as other motorists when operating on the streets”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
What it costs
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
