1. Two
   Four
2. Five
   Six

Four jackstands - one at each corner of the frame - are placed underneath the car while it's raised. This ensures it's supported and doesn't fall on the mechanic.

1. Stand in front of the vehicle
   Stand in back of the vehicle
2. Stand to the side of the vehicle
   Stand anywhere near the vehicle

It's OK to be near the vehicle while its moving into the service bay so long as you're not in front. This can potentially lead to serious injury.

1. Never
   Only when there's a lot of work
2. Only when management visits the area
   Only when there's less room to store vehicles

Exits and stairwells should never be blocked. If there's an emergency, workers and customers have nowhere to go.

1. Safety goggles
   Rubber gloves and boots
2. A harness
   Thick clothing

Safety googles prevent any debris or foreign objects in the car's underbelly from falling into the mechanic's eyes. A mechanic needs to see what they're working on to make sure all goes well for the customer.

1. The floor
   The work bench
2. The power station
   The tire changer

A grinder should always be firmly attached to the work bench. This ensures it doesn't move or jiggle during a job.

1. Knife or cutting blade
   Wire brush
2. Crowbar
   Anything pointy will do

A wire brush is designed to get rid of oxidized rubber and dried soap solution safely. Other tools were not specifically built for this task.

1. The right side of the tire
   The left side of the tire
2. Both sides of the tire
   The height of the tire

Checking both sides of the tire is the only way to ensure that the beads are even with each other. Doing only one side will not give you an appropriate idea of where the beads stand and could lead to trouble on the road.

1. Lay them out flat on the floor.
   Remove them altogether.
2. Keep them only in areas with no traffic.
   Make sure they're washed and always look presentable.

Rugs and mats that don't lie flat should be straightened out or removed to prevent trips and falls. This helps to avoid injuries.

1. Ignore them when things are going smoothly.
   Obey them at all times.
2. Limit their presence to prevent panic and fear.
   Put dozens up to make the garage or office look professional.

Safety and danger signs are not decorations. They should always be obeyed.

1. They can be placed on top of desks and tables.
   They should always be firmly on the ground.
2. They are not necessary if you can reach an item by tip-toe.
   They are wobbly and unreliable.

If an object is high up, you'll need a ladder. Place it firmly on the ground and careful walk up. Never place it on an unstable surface.

1. Only when necessary to see what's wrong with it.
   No. This puts people in danger.
2. Yes, but only if you stay perfectly still.
   Yes, but only if an auto shop employee is driving the truck.

The bed of a pickup truck does not contain seat belts. Therefore, riding in it is unsafe.

1. A 3-point contact
   A 2-point contact
2. A 4-point contact
   A 6-point contact

One should use a 3-point contact involving either one foot and both hands or both feet and one hand. This lets others know that they're exiting or entering a vehicle.

1. All the time
   Only when the vehicle is moving
2. It doesn't matter - seat belts aren't that important.
   Only when one is working on the inside of the car

In an auto shop, the environment is unpredictable. Therefore, to ensure safety at all times, one should always be wearing a seat belt while inside a moving vehicle.

1. Honk the horn.
   Wave to all nearby employees.
2. Shout to get attention.
   Look over their shoulder to ensure no one's around.

Honk the horn to let all nearby employees know that you're backing the vehicle up. This lets them know to steer clear.

1. Lightly honk the horn.
   Drive very slowly.
2. Turn the vehicle's headlights on.
   All of the above

All three should be done to get the attention of both employees and customers. This will let them know to steer clear of the entering vehicle.

1. It can be left alone if the vehicle is moving slowly.
   It should be removed from the vehicle.
2. It should be tied or latched down.
   It can be left alone if the vehicle is traveling a short distance.

All equipment in the bed of a truck should be tied or latched down at all times. This ensures that it won't move about and cause danger.

1. 5 mph
   7 mph
2. 10 mph
   12 mph

A vehicle should be going no faster than 5 mph when traveling into an auto shop. This speed is low enough to keep conditions safe and prevent injury to others.

1. Positive lock-down device
   Negative lock-down device
2. Bolts
   Other employees

The positive lock-down device is used to keep a wheel held by the tire machine. A moving wheel prevents a job from being done properly and can hurt others.

1. Kick it.
   Get a manager's opinion.
2. Use an air pressure gauge.
   Feel around for any soft spots.

An air hose with an air pressure gauge is used to determine a tire's stability. Too much or too little pressure can damage a tire, and this tool allows you to be sure.

1. Put the emergency brake on and chock the wheels.
   Dust off the odometer to ensure the customer can see it clearly.
2. Clean the exterior with a rag.
   Make sure all windows are shut.

Putting the emergency brake on and chocking the wheels ensures that the car will stay in one place. If the vehicle moves on its own, people may be put in danger.

1. 20 pounds
   30 pounds
2. 40 pounds
   50 pounds

40 pounds is the maximum amount one can exert when seating the beads. Any more can lead to damage.

1. Wear leather gloves.
   Try to be careful so as not to cut oneself.
2. Get an associate's help.
   Be as quick as possible.

Wearing leather gloves is the best way to prevent injury to one's fingers when removing foreign objects from a tire. The leather is strong enough to keep foreign objects from damaging the skin.

1. Horizontal position
   Vertical position
2. Backward position
   Side position

Placing the tire in a horizontal position allows a mechanic to get a full view of the tire. Any other position or direction may affect the mechanic's sight pattern.

1. Up
   Down
2. East
   West

A wheel's narrow edge should always be facing up. This allows the mechanic to properly remove it from the vehicle.

1. Rim flanges
   The tires themselves
2. The wheels
   The base of the car

Beads are always loosened from the rim flanges. This allows the inside of the wheel to be properly lubricated.

1. Hands and knees
   Hands and calves
2. Hands and hips
   Hands and waist

Using your hands and hips is the best way to ensure your body encompasses the tire. This will also give it the most support.

1. Wrench
   Pipe
2. Make-shift bar
   Both 2 and 3

Pipes and makeshift bars do not have the strength to support wheels. Thus, they shouldn't be used for bead work.

1. Bottom bead
   Top bead
2. Right bead
   Left bead

The bottom bead should always go in first. This provides the proper support for the remaining beads.

1. Have an associate on standby.
   Ensure the bottom bead is sturdy.
2. Start the tire changer.
   Both A and B

Starting the tire changer allows one to remove the top bead. It's the first bead that should be removed in the tire changing process.

1. Changer hold-down cone
   Metal valve
2. Changing clamp
   Wrench and screws

A changer hold-down cone is the proper tool for fastening a wheel to a changer. Such an item was built with this job in mind.

1. Waist height
   Knee height
2. chest height
   Neck height

The axle hub should always be positioned at waist height. This ensures the mechanic has enough space to work while lessening the chances of injury.

1. The car
   North
2. East
   You

The tire and wheel should always be facing you when being positioned on the floor. This way, you can be in a comfortable position when working on the vehicle.

1. Use two people.
   Stack tires below shoulder level.
2. Avoid rolling them.
   All of the above

All of these options should be carefully understood and followed when loading and unloading tires from a vehicle to ensure top-level safety. Not following one or all these steps may result in a rolling tire, which may lead to damage or injuries.

1. Hammers
   Chisels
2. Punches
   All of the above

No tool with a mushroom head has any place in an auto shop or garage. They are dangerous, and can damage portions of the vehicle.

1. One
   Two
2. Three
   Four

One should use a mechanical lift to raise a vehicle about one foot above the ground. This gives the mechanic enough space to work on its underside while being able to perform a close, hands-on evaluation without having to strain.
