Speeding Allegations, Evidence, and the Use of a Motion to Dismiss
When a person receives a court summons for an alleged speeding offence, particularly after responding under the Single Justice Procedure and entering a not-guilty plea, it is important to understand the correct legal route for defence.
Motion to Dismiss: What It Is and What It Is Not
A motion to dismiss is a procedural application. It is used where a case is legally flawed, for example:
- The court lacks jurisdiction
- Mandatory procedures were not followed
- The prosecution has failed to comply with statutory requirements
A motion to dismiss is not normally used where the issue is factual innocence. If the defence is that the offence could not have been committed by the accused, that matter is determined by evidence at trial rather than by dismissal on procedural grounds.
Defending on the Basis That the Offence Could Not Have Been Committed
Where a defendant can demonstrate that they were elsewhere at the time of the alleged offence, this can form a strong defence. In driving cases, this may include:
- Evidence of being at work
- Tachograph records confirming the location and activity of a commercial vehicle
- Employment or delivery records supporting the timeline
The burden remains on the prosecution to prove the offence beyond reasonable doubt.
Vehicle Identification and the Issue of Cloned Number Plates
In cases involving alleged motoring offences, the prosecution must prove that the vehicle involved was in fact the defendant’s vehicle.
The issue of cloned registration plates is well documented. In 2018, Essex Police publicly estimated that there were potentially 1.75 million cloned vehicles on UK roads at that time. Since then, the expansion of ANPR camera systems and clean air charging zones has increased both the detection of vehicles and the incentive for plate cloning.
If a defendant raises a reasonable argument that a vehicle displaying their registration number may have been a cloned vehicle, the prosecution must rebut that argument with evidence.
Driver Identification and Reasonable Diligence
Under section 172(4) of the Road Traffic Act 1988, a person is not guilty of failing to provide driver details if they can show that:
- They did not know who the driver was
- They could not, with reasonable diligence, have ascertained the driver’s identity
If the alleged offence involves a vehicle that may not have been under the defendant’s control, or may not have been their vehicle at all, this statutory protection becomes particularly relevant.
Key Legal Principles to Remember
- A motion to dismiss applies to legal or procedural defects, not factual disputes
- Evidence proving the accused could not have committed the offence is a matter for trial
- The prosecution must prove the vehicle involved was the defendant’s vehicle
- The prosecution must meet the standard of proof beyond reasonable doubt
- Statutory protections exist where driver details cannot reasonably be provided
Summary
Where credible evidence exists showing that an accused person was elsewhere at the time of an alleged speeding offence, and where questions arise over vehicle identification or plate cloning, a not-guilty outcome is realistically achievable. The correct approach is to rely on evidence, statutory protections, and the prosecution’s burden of proof rather than seeking dismissal on procedural grounds alone.
