An adequate space margin is one that provides a driver with

• Visibility
• Time
• Space 
• All of the above

One reason to develop the habit of checking behind you using your mirrors is 

• help you to avoid collisions when conditions changes suddenly
• be able to pull over for fire trucks and ambulances 
• know if a police officer is behind you
• know the make a color of vehicles around you.

The main area of focus to guide your vehicle is the 

• hood of your vehicle
• right edge of he road
• your intended path of travel
• center line of the road

To develop a selective search pattern, you should

• Know where to direct your search
• Classify information into major groups.
• Both A and B are correct
• Neither A nor B is correct

Drivers with poor visual habits 

• prepare for stops and turns far enough in advance
• are rarely surprised
• respond to changes in the traffic environment
• tend to be unaware of their own speed

When you are driving, it is most difficult to control the space to your 

• rear
• front
• right side
• left side

When driving, blind areas include those areas you cannot see when

• checking mirrors
• ground viewing
• scanning from side to side
• all of the above are correct.

When using ground viewing you are not looking for

• Shadows
• the color of a vehicle to your side
• pavement markings
• road conditions

All of the following are off-road obstacles except:

• Shrubbery
• Signs
• Buildings
• other drivers

A reasonable and proper speed for any set of conditions is a speed that: 

• Will not result in a violation
• Allows you to avoid spinouts
• Allows time to adjust your radio while moving
• Assures a safe travel path
