True or False: WreckMaster recommends at a minimum the use of a 4 Point Tie-Down method of securing a motor vehicle on a carrier.

Is it necessary for every towing company dealing with traffic incidents to have a Temporary Traffic Control (TTC) plan?

A detailed circle check is performed when?

True or False: Any lane closure requires compliance with the MUTCD Standards.

True or False: Gross Combination Weight is the total weight of all the axles on the ground.

True or False: Secondary attachment chains should be attached between a towed vehicle and the tow truck, crossed and to an independent and secure attachment point.

True or False: When a towing and recovery operator arrives on the Scene of a Multi-Agency Accident, the operator should park their truck on the opposite side of the road from the accident so the traffic going through the accident will slow down and look at what is happening at the accident.

True or False: When towing most motor vehicles, WreckMaster’s recommended height for the lifted axle tires is to have the bottom of the tire or wheel be the same approximate height as the center of the drive axle on the tow truck or carrier.

True or False: The Operator should know the Work Load Limit for the size and grade of chain being used.

True or False: You as the Towing Operator, are not the most important person at any incident scene.

Is it ever permissible or acceptable to place one’s self under a suspended load?

True or False: WreckMaster uses the word “SCENE” as a five-point guide for tasks involving a breakdown, transport or recovery job. The “N” stands for the task of explaining the recovery plan.

A car requiring service has a static weight of 3,197 lb. It’s front axle has a weight of 1,726 lb. while the rear axle weighs 1,471 lb. Both front tires are flat and the tie-rod has been damaged. The front tires are not going to turn or rotate. The rear axle has no damage and the tires will turn freely. The car is setting on a hard packed grass surface.

The total resistance to be moved if a winching method is employed?

True or False: When parking a tow truck and applying all of it’s brakes, Damage Resistance is created. The factor or rate used to calculate Damage Resistance is 0.15.

It is recommended the tip of a hook be pointed up?

Which two of the following hooks are NOT found in use on a carrier / rollback?

Steel Core Wire Rope is what percentage stronger than Fiber Core Wire Rope?

Generally, while responding to an emergency police dispatched call, is it permissible to exceed the posted speed limit?

What is the WLL of 3/8 G-8 alloy chain?

In the following, calculate the force required to overcome the resistance:

The rear wheels of a camper are on soft grass. The front wheels are on asphalt. It’s 1,600 lb boat trailer is on soft grass. Estimated weight of the rear axle is 5,400 lb. The front axle weight is 4,700 lb. The force required to overcome the resistance is?

A 12,000 lb step van has upset. The 5,520 lb rear axle of the van is blocking the driving lane. The decision has been made to clear the driving lane by winching the rear axle of the  van off of the highway at a 90 degree angle. What would the minimum weight of a tow truck need to be, to provide enough anchor-ability to prevent itself from being pulled towards the casualty?

True or False: The RPM range for the PTO needs to be above the manufacturer’s setting.

A 14,000 lb concrete vault has shifted on the deck of a lowboy trailer. The trailer is level and the load needs to pulled two feet on the trailer’s wooden deck. It will require a pull of:

What are the two types of ratings that may be referred to when selecting chain or wire rope:

True or False: The term “quenched and tempered” refers to a heat treating process to strengthen chain.

What maximum rolling resistance factor or rate must be calculated for a vehicle on level hard gravel?

What maximum rolling resistance factor or rate must be calculated for a vehicle on level soft grass?

What maximum rolling resistance factor or rate must be calculated for a vehicle on level asphalt?

In estimating a pull, the term “resistance” refers to:
