In the UK, there are certain laws in place that determine how police officers must undertake roadside drug tests, and under what circumstances they can do so. To refuse a drug test without knowing whether you have the right to can lead to serious legal consequences if you are then found to be guilty of drug driving, so understanding your rights in the face of this situation is essential.

Here, we explore the legal grounds and procedures for police drug testing, what you should do if you are asked for a test without proper cause, and the steps to take if the proper protocol is not followed by the police. Understanding your rights and the police's obligations is key to making sure your rights are upheld.

The Laws of Police Drug Testing in the UK

Police drug testing is governed by strict laws and regulations to balance public safety with individual rights. The primary legislation is the Road Traffic Act 1988 and the Misuse of Drugs Act 1971, complemented by various pieces of secondary legislation. Under these laws, police are granted the authority to conduct drug tests in specific circumstances.

Reasonable grounds under which police can request a drug test include:

• Driving under the influence: if a police officer suspects you are driving under the influence of drugs, they have the right to stop you and administer a roadside drug test. This is often based on observable signs such as erratic driving, slurred speech, or the smell of drugs.
• After an accident: if you have been involved in a traffic accident, the police may require you to take a drug test to rule out impairment as a contributing factor.
• Arrest: upon arrest for certain crimes, especially those that suggest drug involvement, the police might require a drug test as part of the investigation process.
• Public safety: in scenarios where your behaviour suggests drug impairment and poses a potential threat to public safety, a drug test may be deemed necessary.

The Proper Procedure for Police Drug Testing

For a police drug test to be lawful and its results valid, officers must stick to a stringent set of procedures. These ensure the test is carried out fairly and respects your rights:

1. Clear communication: the police officer must clearly state the reason for the stop and their intention to conduct a drug test. You should be informed about your rights, including consequences of refusing the test.
2. Conducting the test: the first step is usually a preliminary impairment test, which may include eye and balance tests, to establish if you are impaired. If the officer suspects drug use, they might use a roadside drug screening device to test saliva for substances like cannabis and cocaine. A positive initial test will typically lead to you being arrested and taken to a police station for a blood or urine test, which provides evidence.
3. Documentation and handling: all steps and results should be thoroughly recorded and documented. To prevent contamination, samples must be handled and stored according to strict guidelines.
4. Detainment and charges: if the final test at the station is positive, you may be charged with drug driving. The police must explain the charges against you and your rights going forward.

It is important to remember that throughout this process, you have rights designed to protect you, including access to legal counsel. If at any point you feel these procedures are not being followed, it’s within your right to voice your concerns. However, whether the police adhere to them that is a matter we would have to consider. 

Your Rights and What to Do if You Are Asked for a Drug Test Without Proper Cause

Understanding your rights is vital when facing a police request for a drug test, especially if you believe there is no valid reason for it. You are entitled to ask the officer why they believe a drug test is necessary. They must provide a clear, legally sound reason based on observable evidence or circumstances.

Before submitting to any test, you have the right to consult a solicitor. However, please note the police could reject this if it delays the overall process. A solicitor can provide immediate advice on your rights and the best course of action. While you should assert your rights, it is essential to remain calm and cooperative. Confrontational behaviour might complicate the situation. In addition, you should note that you must not refuse or fail to provide a specimen, as this can result in an additional charge. 

If possible, make a note of the time, location, officers involved, and the reasons provided for the test. This information could be vital if you need to challenge the procedure later.

Regardless of the test outcome, if you believe it was conducted without proper cause, contact a solicitor as soon as possible. They can guide you through the process of challenging any potential charges and the legality of the test.

Recourse if Proper Procedures Are Not Followed

If you believe the police have failed to follow the proper procedures during a drug test, or your rights were infringed upon, you have several options:

• Legal action: seek advice from a solicitor who specialises in police conduct. They can assess the validity of your case and guide you on the next steps.
• Gathering evidence: gather any evidence you have, including the notes you took during the incident, any witness statements, and medical reports if you were tested. Your solicitor can help obtain police records and other evidence that might be inaccessible to you.
• Continuous monitoring: if you're involved in an ongoing case, keep a detailed record of all interactions and developments. This will be invaluable for your legal team.

When confronted with a drug driving conviction, act promptly and seek legal advice to ensure your case is handled correctly and your rights are upheld.
