Interstate driving — West Virginia Permit Test
Interstate driving on the West Virginia permit test — 10 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Slower traffic on an interstate should stay in the right-hand lane except when passing.
A slow vehicle in a fast lane forces the traffic behind it to change lanes, which is where the crashes come from.
Traffic already on the interstate has the right-of-way over traffic entering it.
A merging driver who assumes they will be let in is planning around somebody else’s attention.
A driver merging from an acceleration lane should match the speed of the traffic already on the interstate.
Joining slowly forces the traffic behind to brake at 70 mph, which is how a merge becomes a pile-up.
A driver should not stop on an entrance ramp or in the acceleration lane.
A vehicle stopped in the acceleration lane is met at speed by the next driver expecting a clear run.
A driver leaving an interstate slows in the deceleration lane rather than on the interstate itself.
Braking in the through lane surprises the driver behind, who is still traveling at highway speed.
Interstate shoulders are for disabled vehicles only, not for changing drivers or reading a map.
A parked car on the shoulder is struck by drivers who drift toward what they are looking at.
A driver should not stop in an exit gore, the triangular area between the through lane and the exit ramp.
A driver who has missed the exit cuts back across the gore and hits whatever is sitting in it.
A driver should never make a U-turn on an interstate, and the crossovers in the median are for police and emergency vehicles.
A U-turn across an interstate puts a slow, sideways vehicle in front of traffic doing 70 mph.
Even-numbered interstates run east to west and odd-numbered interstates run north to south.
The number is a map when a driver is deciding between two exits at speed.
A three-digit interstate number beginning with an even digit is a beltway or bypass around a city, and one beginning with an odd digit is a spur route.
Choosing the wrong one at speed sends a driver into a city center instead of around it.
On the test
Which lane should a driver use on an interstate except when passing?
The right-hand lane. A slow vehicle in a fast lane forces the traffic behind it to change lanes, which is where the crashes come from.
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.
