Drivers Ed Test#3

Why is Urban Driving is Challenging

Density of vehicals

Proximity of Hazards

IPDE

Identidy- inporrtant info on driving scene

Predict - when and where points of conflict will develop

Decide - how when where to communicate, adjust speed

Execte - correct actions to avoid conflicts and ensure safety.

What is easier?

Searching for one specific number or recalling the whole number?

A specific number because the search is moe limited.

Urban Traffic

Traffic is denser and hazards are closer.

If you can’t increase the distance between your vehicle and a hazard, you must change your lane position, slow, or stop to give yourself time to avoid the conflict

Urban Traffic - following disance

3 second rule

Look over, through, or around the vehicle you are following.

Urban Traffic - where to stop

there will be sudden stops ate

• intersections

• lanes next to parked vehicles

• Buisness driveways with a high volume of traffic

Charger Tailgaters

approaches with excessive speed and wants to pass

One Pace Tailgaters

Likes to travel at a set speed, usually above the speed limit; usually above it

Habitual tailgaters

Frequently distracted and doesn’t realize that they are tailgating

How to manage tailgaters

• maintain a safe space from the vehicle ahead

• go into lane position 3

• Signal early for turns, stops, and lane changes. Make sure to flash brake

• In extreme situations, change lanesor pull over to let them pass.

avoiding conflicts

look for the following clues

• rear exhaust

• headlights/taillights

• tires turned toward roadway

• at the base of the cars for pedestrians’ feet

Rual Areas fun facts

• collisons in rural areas account for twice as many deaths than in urban

• At night, bad lighting causes difficulty seeing

  • The speed limit is the max under ideal conditions

Factors that affect safe speed selection

• other highway users

• inclement weather

• hills

• curves

• intersections and narrow roads or lanes

Turning tip

When turning, make sure to keep your front wheels straight. If you don’t, you will be pushed into oncoming traffic

Passing (three stages)

• Decide to pass

  • is it legal

  • is it worth it

  • is it safe

• prepare to pass

• execute the pass

How many seconds do you need to complete a pass?

10 - 15 sec

No Passing situations

• 700 ft prior to a hill

• within 100 ft of an intersection/railroad crossing

• on two lane bridges or an underpass

• on curves

• when vehicle ahead is traveling at the speed limit

What is expressway driving designed for?

low risk, high speed traffic

vehicles can only enter and leave via interchanges

types of interchanges

-cloverleaf

diamond

trumpet

all directional

Three parts of expressways

Entrance ramp

acceleration lane

merging area

How to tell if an expressway lane is open/close

• a green arrow or x means oppen

• a yellow x means the lane ahead will be closed

• a red x means the lane is closed

What is another word for a bunch of vehicles?

A wolf pack

Special expressway problems

Most expressways have toll plazas

Types of toll booths

• automatic (customer deposits money)

• attendent operated

• electonic (EZ pass)

Pull out areas

where an additional right lane is available for slower moving vehicles

Runway vehicle ramps

Provide a place for vehicles to safely stop if they experience braking problems

Altitude

can cause:

• shortness of breath

• faster heartbeat

• headache

• reduced concentration

• Drowsiness

How does altitude affect vehicles

• climbing power is reduced

• slower acceleration

• temp of water in radiator can increase = overheating

Excess Heat

• check radiator fluid

• check tie pressure

• check battery fluid

Snow Storms

• gentle acceleration, steering and braking

• Don’t race a cold engine

• Don’t set your parking break

Skidding

• steer opposite the way your vehicle is skidding

• use controlled braking to reduce vehicle speed and to maintain control of the vehicle

types of skidding

1. over power: applying too much power to drive your wheels

2. Over breaking: when your wheels stop and the car is still moving after

3. Front wheel: if you turn the steering wheel and the car wants to go straight

4. Rear wheel: if you are steering too much and your vehicle stats to move off target

Tire Blowout

When the tire blows out, the vehicle pulls in the direction of the deflated tire. You must steer firmly against the pull of the vehicle

How to react to a flat tire

• park car in a safe, flat surface

• set up reflectors for visibilty

• check owners manual for special procedures

Brake failure fun fact

there is a two part breaking system.

So, if one fails, the other part still brakes two wheel

Power Brake failure

occus when the engine looses power. The brakes have not failed; you just need to push the brake pedal harder

Brake fade

occurs after continuous hard braking. To regain full braking ability, stop the vehicle and let the brakes cool

How to communicate to other drivers

horn and hazard flashers

Flooded engine

occurs when there is too much fuel In the engine

When to swerve

when you believe that braking will not stop a collision

Steps for when in a collison

1. S top immediately

2. A id the injured

3. P revent further damage (warn others)

4. S end for police

5. E xchange info
