The “Time – the key to judgment” section of the Saskatchewan Driving Practice Test highlights the importance of timing in safe driving.

Saskatchewan Driving Test - Chapter 4-3a: Time – the key to judgment

1 / 30

What should you do if a large truck or van ahead blocks your view of traffic in front of it?

Drop back to more than three seconds until you can see around it

Move closer to see better

Change lanes immediately regardless of traffic

Flash your lights so it moves

2 / 30

What should you do with your following distance when driving conditions are less than ideal (e.g., poor weather or road conditions)?

Reduce following distance to stay closer to other vehicles

Ignore following distance and just slow down

Keep exactly three seconds regardless

Increase your following distance beyond three seconds

3 / 30

Besides decision-making, what else must your three seconds of following distance allow time for?

Reaction time to move your foot off the accelerator and apply the brake

Signalling lane changes

Shifting into neutral

Checking your mirrors repeatedly

4 / 30

In a potential collision situation, what will you use much of your three seconds for?

Checking your navigation system

Honking at other drivers

Adjusting the radio

Identifying the problem, predicting the outcome, and deciding what to do

5 / 30

After guessing how many seconds away a stationary object is, what should you do next?

Change lanes to get closer

Start counting seconds until your front bumper reaches the object

Stop the vehicle to check your watch

Apply the brakes right away

6 / 30

Under ideal conditions and alertness, what can you typically accomplish within a three-second following distance?

Bring the vehicle from highway speed to a complete stop every time

See the problem, decide, react, and begin braking

Change lanes twice

Stop without ever using the brakes

7 / 30

How far ahead should you generally be looking to spot problems early enough to respond safely?

Only as far as the vehicle immediately in front of you

Exactly 3 seconds ahead

Anywhere from 12 to 60 seconds ahead

Only 2 seconds ahead

8 / 30

Why is eyesight described as the most important sense for driving?

Smell is more important than sight

Hearing is rarely used in driving

Touch is more reliable than sight

Your eyes pick up most of the information you need to drive

9 / 30

In an emergency or skid, what should you do with your eye focus to help maintain control?

Focus only on the rear-view mirror

Look at the obstacle you fear hitting

Close your eyes and brake hard

Look where you want to go and steer there

10 / 30

Compared to 50 km/h, how far back will you be at 100 km/h if you maintain a three-second following distance?

Twice as far back

Half as far back

The same distance back

Three times as far back

11 / 30

When steering through a curve, where should you focus your gaze?

Directly down at your speedometer

At the outside edge of the road

At the inside of the curve to where the centre lines vanish

In your rear-view mirror

12 / 30

What is the advantage of looking well ahead instead of only reacting to the brake lights of the vehicle in front?

You no longer need to check mirrors

You can drive faster than the speed limit

You can respond to the cause of the problem, not just to another driver’s reaction

You can ignore following distance

13 / 30

To steer straight ahead, where are you advised to look?

About 12 seconds directly ahead of where you are sitting

At the oncoming traffic’s headlights

At the road immediately in front of the bumper

At the hood ornament

14 / 30

What is the minimum recommended following distance under ideal driving conditions?

Three seconds

Ten seconds

Half a second

One second

15 / 30

If you guessed 15 seconds to an object, but it was actually 8 seconds away, how should you adjust?

Guess a higher number next time

Keep guessing 15 seconds

Guess a lower number next time

Stop using time for judgment

16 / 30

When do you stop counting to determine your following distance?

When the vehicle ahead changes lanes

When your front bumper is beside the chosen object

When you pass a driveway

When the vehicle ahead begins braking

17 / 30

At which speeds are you advised to practise estimating time and distance after starting at one speed?

Only at 120 km/h

Speeds you commonly drive, such as 100, 80 and 50 km/h

Only in school zones

Only when driving in city traffic

18 / 30

In which situation would you likely need more than three seconds to avoid a collision?

If traffic is very light and visibility is perfect

If you are driving at very low speed in a parking lot

If the driver ahead hits a fixed object or has better braking and traction than you

If you are the only vehicle on the road

19 / 30

What is the danger of looking away from the road at mirrors or the instrument panel while steering through a curve?

You will not maintain precise control over your steering

Your headlights will turn off

Your brakes will stop working

Your seat position will change automatically

20 / 30

Why is it unwise to reduce your following distance just to prevent other drivers from “cutting in”?

You give up sight distance, planning time, and relaxed driving for only a few seconds’ gain

It increases your fuel economy

It guarantees you will arrive late

It makes lane changes illegal

21 / 30

What is the main reason drivers are encouraged to use time rather than distance to judge how far ahead things are?

It is easier to estimate time accurately than physical distance while moving

It only works when objects are not moving

It makes you drive faster

It eliminates the need to look ahead

22 / 30

What basic principle explains how your eye use affects your steering?

You steer where the mirrors are pointed

You steer where the wheel vibrates least

You steer where you look

You steer where you hear sounds

23 / 30

When estimating your following distance from the vehicle ahead, what kind of object should you choose?

The vehicle’s brake lights

A cloud in the sky

A moving pedestrian

A stationary object on or near the road

24 / 30

What is the first step in learning to estimate how far ahead a stationary object is in seconds?

Wait until the object is right beside you

Speed up to reach the object faster

Pick a stationary object on or near the road

Immediately begin counting

25 / 30

How are you instructed to count seconds to estimate time while driving?

Say “thou - sand one, thou - sand two, thou - sand three” at a normal speaking rate

Use your watch or phone every time

Only count inside your head, never out loud

Count “one, two, three” as fast as you can

26 / 30

Why should you begin practising time judgments at a single, consistent speed?

It is illegal to change speeds while practising

The relationship between time and distance varies with speed

It only works at high speeds

Time does not change with speed

27 / 30

Why does a three-second following distance automatically increase the physical distance between vehicles as speed increases?

Because three seconds becomes longer at high speed

Because the vehicle covers more metres per second at higher speeds

Because lane markings get closer together

Because the speedometer resets

28 / 30

When do you start counting to measure following distance behind another vehicle?

When the light turns green

When you begin braking

When you first see the vehicle ahead

When the back bumper of the vehicle ahead is even with your chosen object

29 / 30

When following a motorcycle or large truck, what is recommended regarding following distance?

Use a following distance longer than three seconds

Reduce your following distance to less than three seconds

Follow at exactly one second

Ignore following distance and watch only brake lights

30 / 30

How should you respond if your measured following distance is less than three seconds?

Drop back and check again until you reach at least three seconds

Turn on your hazard lights

Maintain your current distance

Speed up to pass the vehicle ahead

Your score is

This section teaches drivers how to accurately judge distances, reaction times, and stopping times in various road situations. Understanding the time needed to make safe turns, stop at intersections, or react to hazards is critical for preventing accidents. The practice test evaluates a driver’s ability to manage speed and maintain safe following distances. Mastery of timing and judgment helps new drivers anticipate potential dangers, make better decisions, and contribute to safer roads across Saskatchewan.

Challenge yourself with the SGI practice test study questions, working through them repeatedly until you can confidently explain the underlying concepts without referring to your notes. This method will enhance your understanding and mastery of the material.
