What is a Theory Test?

The theory test is mainly to test your knowledge of the Highway Code, but it also tests your attitude and common sense.

Who needs to take the Theory Test?

If you are a learner driver you must take and pass your theory test before you book your practical test. If you already have a driving licence you might not have to take another theory test if you want to start driving a different vehicle.

How much does it cost?

From the 1st April 2008 the standard fee for car and motorcycle is £30.

Where do I book?

You can book directly with the DSA.

What to expect on the exam day

The theory test is made up of two parts; the multiple choice part and the hazard perception part. You need to pass both parts to pass the theory test. Once you have passed the theory test you can then apply to take your practical driving test.

Part 1: Multiple Choice

Before the test starts you’ll be given instructions on how the test works.

You can also choose to go through a practice session of the multiple choice questions to get used to the layout of the test. At the end of the practice session the real test will begin.

A question and several answer options will appear onscreen and you have to select the correct answer to the question by touching the screen. Some questions may require more than one answer.

For cars and motorcycles you’ll be asked 50 questions in 57 minutes and the pass mark is 43 out of 50.

You can navigate between questions and ‘flag’ questions that you want to come back to later in the test. After the multiple choice part you can choose to have a break of up to three minutes before the hazard perception part starts.

Part 2: Hazard Perception

After the break you’ll then be shown a short tutorial video clip about how the hazard perception part works.

The hazard perception part is also delivered on a computer but you respond by clicking a button on the mouse. You’ll be presented with a series of 14 video clips which feature every day road scenes. In each clip there’ll be at least one developing hazard, but one of the clips will feature two developing hazards.

To achieve a high score you’ll need to respond to the developing hazard during the early part of its development. The maximum you can score on each hazard is five.

You won’t be able to review your answers to the hazard perception test; as on the road, you’ll only have one chance to respond to the developing hazard.

The pass mark for the car and motorcycle hazard perception part of the theory test is 44 out of 75

After the Test

At the end of the hazard perception part of the theory test you’ll be invited to answer a number of customer survey questions.

You don’t have to answer the questions if you don’t want to, and any information given is anonymous and confidential. The survey questions don’t affect the result of the test.

When you have finished the test you may leave the examination room. Once you have left the room, you’ll not be allowed to enter it again. You’ll then be given your result by the test centre staff.

How to prepare

We advise you to have taken some driving lessons with an instructor before before taking your Theory Test. We would also recommend that you do some Practice Theory Tests on software or on our website Theory Test Pass. It will also allow you to practice your Hazard Perception.

 

A Cocaine drug test is the method or the technique used to know the presence of cocaine in the body. The testing is done by examining various specimen of the human body like the urine, hair, saliva and even sweat.

Types of cocaine Drug Testing: The different types of testing and quantifying of the cocaine content in the human body are

Hair Testing: Hair testing is one of the effective ways of testing for the cocaine content in the human body over a long period of time. Whenever any substance enters the human body, it deposits a residue in the hair shaft, which will show its presence till the hair is cut.

Blood Testing: This is one of the expensive testing for the detection of the cocaine in the human body. This may involve a four to six day program, which may involve us to go for a special diet, regulated fluids and a final detoxifying solution.

Saliva Drug Testing: This method is a short-term procedure which can detect the drugs which are been use recently.

Urine Drug Testing: The analysis of urine is most common and inexpensive method of testing for the presence of cocaine in the human body.

Urine Testing for the Cocaine Detection: Urine testing is mostly preferred when compared to other types of tests for detecting the presence of cocaine in the human body. This is mainly because of the following factors:

· These tests are considered to be the most inexpensive tests.

· These are intrusive methods of testing.

· This test can be done at home.

Cocaine (COC) Dip strip Drug Urine Test: This test is a very simple test for detecting the cocaine content in the human body by testing the urine sample. The qualitative detection of the cocaine content is done with the benzoyelecgonine as the metabolites in the urine sample. The cutoff for the test is 300 ng/ml.

Procedure for the test:

1. Remove the test strip from its foil pouch.

2. Holding the strip vertically, carefully dip it into the specimen. Do not immerse the strip past the maximum line

3. Interpret test results at 3 to 5 minutes.

The result of the test can be interpreted by the colour bands that are visible after the test. If two colour bands are observed then the result is negative where as if only one band is visible then the tests are giving a positive result.

Detection Periods and the factors influencing the tests: The detection of the cocaine content in the human body depends upon various factors. They are

· The amount that is been taken and also the frequency of the usage.

· The metabolic rate also influences the outcome of the tests.

· The body mass also may influence the results of the tests.

· The age of the person who is undergoing the test has the influence on the tests.

· The drug tolerance levels also may vary between person to person and this variation in the tolerance will have the effect.

Detection Period: It takes approximately six to eight hours for detecting the presence of the cocaine in the urine sample. Whatever may be the effects of the above factors, the ideal time period for the clearing of benzoyelecgonine is three to five days so the urine sample collected should be not older than three days.

Urine tests for detecting of the cocaine content is certainly the most cost effective and a simple method for testing. These urine tests have made it easier for detecting the cocaine content in the body, as there are even some methods for doing the tests at the home.

Oral Fluid/saliva drug tests are rapidly becoming the ideal process for drug testing at both the home and workplace. Generally they can also detect the specimens of previous few days. Oral fluid based drug tests are as accurate as the urine tests. They can be obtained from quality suppliers in the United States. Specifically, the oral fluid test enables to employ the random drug testing programs, which are the efficient form of drug testing. These tests are likely photocopies the results of the blood tests and the level of intoxication can be estimated, according to the substances in the blood.

Oral Fluids can detect:

• ALCOHOL - Q.E.D. Saliva Alcohol Test (rapid)

• NIDA-5 - THC, Cocaine, Opiates, Amphetamines, PCP

• OTHERS - Benzodiazepines, Barbiturates, Methadone

Features and Benefits of Oral Fluid Testing

The following are the feature of Oral fluid drug testing which even serves as the benefits to the donors:

• Cost Efficiency: The oral fluid is the interceptive test that minimizes or even eliminates the collection fees, reduces the scheduling issues and extensively reduces the lost work time. It costs a lot if the same test is conducted based the urine specimens.

• Control the Process: Oral fluid samples don’t require any special facilities. They can be collected by anytime and at anywhere. There are many alternative for collecting the specimens. It can be collected in a small conference room or in an office. This screening enables the donors to provide the samples and seal it easily, in few minutes. The laboratory reports negative results on the same day and the positive results are confirmed using GC/MS/MS and reports within 2-3 days.

• Adulteration: An oral fluid test can merely abolish the risks evolved in the adulteration. It is virtually impossible to mask the oral fluid samples with drug consumed. The oral fluid testing is often a direct observed system.

• Employee Dignity: The oral fluid test delivers a dignified, secured and evident collection method. The dignity of the collection method is an authentic benefit. It helps in making a good impression. As these are the tests conducted for your loved ones, or for your employees. As a result, this testing is a less embarrassing method to adopt.

Advantages of Oral Fluid Testing over Urine Tests:

Using well-proven technology, saliva tests offer several advantages over urine based tests:

• Oral fluid samples may be collected under direct supervision without donor privacy issues.

• Helps to eliminate sample adulteration.

• Sensitive and specific assays provide accurate test results.

• Non-invasive.

• Ideal for on-site testing. Test may be conducted anywhere and at anytime.

• No additional equipment or operator training required.

• The test kit includes all components like, instruction card to eliminate the errors.

The above information helps the individuals who want to test the drug screening in a simple and easy way.
