How much time a tow truck takes to reach in an emergency?

The cops can get immediate service so they can clear the road and get traffic going. Anyone else has to wait their turn. I have waited two hours for a tow truck.

Depending on the county a lot of factors can effect the time a wrecker takes to get there. In Texas any wrecker with the proper tags and a set up for radios in their truck can show up to a wreck. Usually a wrecker can get there within 15-20 minutes

Varies. Least I had to wait was 45 minutes. One wrecker NEVER showed, so that is infinite. One took two hours, from Florence to Arizona City.

It depends on how busy the tow truck is and how far it has to travel to get to you. It could be a few minutes or a few hours.

It depends on traffic, time of day, day of the week, weather and number of trucks/drivers available. I had to wait 2 hours on a Friday at rush hour once.

What constitutes an emergency for a tow truck?

It takes however long it takes...

I suppose that would depend on where the tow truck is when they are called out. Tow trucks ARE NOT "emergency vehicles" like ambulance or fire trucks. They can't run red lights and sirens to clear traffic in front of them. They'll get there when they can.

Depends on many factors. My experiences have not been positive.

Fjjdyes that makes sense to me
