What is scanning? Scanning means taking in the whole scene degrees around your car. This is a key hazard perception skill that drivers need to use to avoid crashes.

You need to scan constantly for hazards when you drive. Research shows that new drivers are not good at scanning. They tend to focus on the road just ahead of their car. The good news is that new drivers get better at scanning with practice. This section aims to help you become better at scanning so that you can detect hazards before they become a problem for you and other road users. How to scan for hazards when driving To scan effectively you need to move your eyes, your head and perhaps your upper body to get a good view of what is going on right round your car.

This means that you need to look out of the windscreen and the side windows to see what is shaping up ahead and to the sides. You also need to use your mirrors to see what is behind you. But your mirrors can't cover all of the view behind. You always have "blind spots" - areas not covered by your mirrors.

To check your blind spots you need to turn your head and look out the side windows. Blind spots will be different on each vehicle that you drive. Vehicle such as vans or trucks often have more blind spots than passenger cars. Checking the blind spots with a head check is vital when you want to change lanes or when reversing. A scanning routine Experienced drivers constantly scan for hazards when driving.

They do it automatically. To help you become better at scanning for hazards, here is a good routine to develop. Look up to 12 seconds ahead. Scanning this far ahead gives you a chance to spot hazards that are shaping up well in advance eg a broken down truck, an accident, the road narrowing to one lane. You will also have time to avoid them.

In heavy traffic, you may not be able to look 12 seconds ahead. But you are likely to be travelling more slowly which helps make up for this. Scanning far enough ahead may mean looking through the windows of vehicles ahead of you to see what is happening. For example, by doing this you will know in advance if a car ahead is braking as you will see the brake lights come on several cars ahead. This gives you more time to brake if you have to. Scanning means that you are not just looking at the vehicle immediately in front of you.

Looking ahead also means scanning from side to side for hazards on the roadside or at intersections. Hazards may be parked cars, cyclists or pedestrians. Check your mirrors every seconds. Things change behind and beside you when you drive. Unless you check your mirrors you won't know if someone is doing something such as trying to overtake or if there is a police car or ambulance coming up quickly.

Check your blind spots. Scanning ahead and checking your mirrors is usually enough when you are driving along in the same lane without turning or changing lanes. However, if you need to turn or diverge right or left, you need to know what is in the blind spots. Head checks enable you to check your blind spots. This scanning routine is shown in the next picture. Your scanning routine needs to be constantly repeated as you drive. Of course if you detect a hazard and need to deal with it, this will be your first priority.

But once this has passed, you need to return to your scanning routine. Smart scanning When you are scanning, there is a lot to look at and a lot to take in. It would be impossible to look at everything else that you see in detail. You need to be smart about the way you scan for hazards.

This means sorting or filtering what is important from everything else that is happening. Here are some ways to make your scanning smarter.

Look for change Your vision is designed to pick up movement and change, not what stays the same. This means that moving hazards may be easier to spot than stationary ones like road works or parked vehicles.

This can be a problem because you can get distracted by a fast moving hazard eg a police car coming towards you and miss a stationary one that may be of more immediate concern eg a parked truck blocking your lane. You need to look for both moving and stationary hazards. A hazard perception action plan Through scanning and hazard perception you are trying to:.

See road hazards eg pedestrian waiting to cross the road ahead. Think about what might happen eg pedestrian might walk in front of your car. Think about possible solutions eg slow down, change lanes or increase space between your car and pedestrian, sound horn. Do something to remain safe eg slow down and give the pedestrian more space. Scanning is the "see" part of the process.

Understanding that these three steps are the basis of good hazard perception can be helpful. Of course, all of this takes place very quickly, sometimes in only a few seconds.

This is why you need to practise in real traffic so that hazard perception skills like scanning become automatic. Listening for hazards While driving is mainly a visual task, listening can also help detect hazards. For example, you can often hear its siren before you actually see an emergency vehicle like an ambulance.

Another example is motor cycles - they can be hard to see, but the sound of an engine can let you know there is one nearby. To help you listen for hazards, it is good not to have the radio or stereo too loud when you are driving.

Avoiding fatigue Fatigue being tired and losing concentration reduces your ability to detect and respond to hazards. Research shows that the more fatigued drivers are, the more hazards they fail to notice and the more likely they are to crash. You don't have to drive long distances to get fatigued. Working long hours, partying hard and not getting enough sleep can make you fatigued. The only effective way to avoid fatigue is to get plenty of sleep.

Fresh air, coffee and loud music won't work. Do not drive at times when you would normally be asleep. Commencing a trip late at night or early in the morning, or driving through these hours, can be very dangerous.

If you do drive long distances, take regular rest breaks at least every two hours. Blind spots on your car Ask someone to help you check where the blind spots are on your car. With the car parked safely at the roadside or in a driveway, check that your mirrors are adjusted properly. Roll down the windows.

Ask your assistant to walk very slowly around the car. Watch carefully in the mirrors, but don't turn your head. Call "Stop" when your assistant disappears from view. Adjust your mirrors again and see if you can reduce the blind spot area and still get a good view of the road behind.

Repeat the process with your assistant again. Did you manage to reduce the blind spots? Repeat the process again. When your assistant is in a blind spot, try turning your head to do a head check. Can you see them or does part of the car still block them? Once you have completed this process, you will know where the blind spots are on your car and how large they are. You will also know to what extent head checks compensate for them.

Scanning routine Practise the scanning routine summarised in this section. Start with:. Try it with the vehicle stationary at the side of the road. When you are confident that you have the routine worked out, try it in various speed zones. Start on quieter roads, then progress to busier ones. Using the "one-thousand and one, one thousand and two, one thousand and three" counting technique, practise estimating what scanning 12 seconds ahead looks like at various speeds.

You may be surprised at how far ahead you need to look. Comparing notes on scanning Ask your Qualified Supervising Driver to help you with this practice exercise.

Map out a circular route through a nearby built-up area that will take you about minutes to complete. Include traffic lights, Stop signs and areas where you are likely to come across other road users such as pedestrians.

Ask your Qualified Supervising Driver to drive the circular route, with you travelling in the passenger seat. Scan the road as though you are driving.

Challenges of Night Driving

In this section we will identify the factors of perception and how these factors affect driver performance. Remember to identify potential hazards, predict what other drivers will do, decide what safety measures you should take, and execute safe driving procedures. In order to avoid hitting an overpass, a tractor-trailer was required to utilize a highway on-ramp.

Drive slower when there are many vehicles close together on the road. Otherwise stopping safely will be harder because you have less room.

According to the National Safety Council, traffic death rates are up to three times greater at night than during the day. Highway maintenance vehicles, such as bulldozers, often move slowly on or next to the road. They are usually painted orange. Be prepared to slow down or stop for them.

Scanning for hazards

Because there is a lot of obstacles that end up on the roadway—such as garbage, furniture, tire chunks, road kill, and other debris—drivers constantly need to scan the road in order to drive defensively. There is one rule that the Department of Motor Vehicles recommends all motorists do to avoid collisions with such objects. It advises that drivers should scan the road at least 12 seconds ahead to avoid potential trouble spots and to identify possible road hazards. Every driver needs to be able to see what is in front of him, to the sides, and in the rear. Being able to see everything clearly helps drivers avoid any last-minute maneuvers. This is why it is recommended that drivers look ahead 12 seconds while driving in the city, and 12 to 15 seconds on the highway. In the city, 12 seconds is about one city block, and on the highway 12 to 15 seconds is approximately one-quarter mile.

Two-second rule

Explanation : Never park or leave your vehicle in a tunnel or on a bridge, on or within 50 feet of a railroad crossing, or between a safety zone and the curb. Explanation : Whenever you drive, you should make sure everyone in your vehicle wears a seat belt. In the event of a crash, a person without a belt becomes a projectile, and a danger to everyone else in the vehicle. Explanation : Keep your eyes moving, notice what is happening at the sides of the road, and check behind you through your mirrors every few seconds.

As a defensive driver, you can avoid crashes and help lower your risk behind the wheel. Some drivers speed aggressively.

The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed. It is intended for automobiles, although its general principle applies to other types of vehicles. Some areas recommend a three-second rule instead of a two-second rule to give an additional buffer.

Feb 29, - vehicle is covered to prevent its contents from blowing, dropping achieve the inch distance, even with the driver seat all the way forward, simply by reclining You should be looking at least fifteen (15) seconds ahead.

Телефон звонил не переставая. Джабба решил не обращать на него внимания. - Мидж, - беззвучно выдавил он, - черт тебя дери.

 Да. Это очень важная часть! - заявил лейтенант.  - Это не ребро или палец, как в церквях Галиции. Вам и в самом деле стоило бы задержаться и посмотреть.

 Без воска? - тихо спросила она, обнимая. - Без воска.  - Он улыбнулся в ответ. Она поцеловала .

 Линейная мутация… - еле выдавил Стратмор. - Я знаю.

В служебных помещениях ТРАНСТЕКСТА было черно как глубокой ночью. Минуту он наслаждался полной темнотой. Сверху хлестала вода, прямо как во время полночного шторма. Стратмор откинул голову назад, словно давая каплям возможность смыть с него вину.

Он знал, что задумал Чатрукьян. Отключение ТРАНСТЕКСТА было логичным шагом в случае возникновения чрезвычайной ситуации, а ведь тот был уверен, что в машину проник вирус. К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности. После таких экстренных действий на главном коммутаторе раздавался сигнал общей тревоги. Проверку шифровалки службой безопасности Хейл допустить не. Он выбежал из помещения Третьего узла и направился к люку. Чатрукьяна во что бы то ни стало следовало остановить.

Он редко встречался со Стратмором с глазу на глаз, но когда такое случалось, это можно было сравнить с битвой титанов. Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось. Он отстаивал перед директором свои идеи со спокойствием невозмутимого боксера-профессионала.
