Other warning lights — New York Permit Test
Other warning lights on the New York permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Personal vehicles driven by volunteer fire fighters responding to alarms are allowed to display blue lights, and those driven by volunteer ambulance or rescue squad members can display green lights.
The volunteer in the car beside you is on a call. The light is the only sign of it.
Personal vehicles driven by volunteer fire fighters responding to alarms are allowed to display blue lights and those driven by volunteer ambulance or rescue squad members can display green lights.
Amber lights on hazard vehicles such as snow plows and tow trucks warn other drivers of possible dangers.
A plow throws snow and a tow truck blocks a lane. The light says work is going on.
Amber lights on hazard vehicles such as snow plows and tow trucks or the combination of amber lights and rear projected blue lights on hazard vehicles designed for towing or pushing disabled vehicles, warn other drivers of possible dangers.
Vehicles that display blue, green or amber lights are not authorized emergency vehicles, so a driver is not required to yield to them, though they should yield as a courtesy if they can safely do so.
These drivers have to obey the traffic laws like anybody else. Letting them by is a kindness.
The vehicles that display blue, green or amber lights are not authorized emergency vehicles. Their drivers must obey all traffic laws.
On the test
What light may a volunteer ambulance member display on a personal vehicle?
A green light. The volunteer in the car beside you is on a call. The light is the only sign of it. New York State Driver's Manual, p.35: “Personal vehicles driven by volunteer fire fighters responding to alarms are allowed to display blue lights and those driven by volunteer ambulance or rescue squad members can display green lights.”
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.
