Drug driving in Italy: the rules changed in 2024
Driving after taking drugs is a distinct offence from drink driving, punished at the level of the highest alcohol band, and the testing is completely different. A reform of the Highway Code in 2024 changed the wording of the provision, and what the prosecution now has to prove is the central question in every one of these cases.
Why it is not like alcohol
Alcohol has a number. A breath reading places the driver in a band, and the band determines the offence. Drugs have no equivalent: substances remain detectable in the body for days or weeks after any effect has passed, so a positive result does not establish that the person was affected while driving.
That gap between detection and effect is the whole defence, and it is why the 2024 reform matters. Where the offence required proof of an actual state of impairment, a positive test alone was not enough. The change to the wording has moved that debate, and it is being argued in every court in the country.
How testing works
| Step | Content | Note |
|---|---|---|
| Roadside screening | Saliva or non-invasive testing | A screening device, not evidence of the offence |
| Confirmatory analysis | Carried out by a qualified facility | This is the evidence |
| Refusal | Punished as the offence itself | Art. 187 Highway Code |
| Blood taken in hospital | Consent and chain of custody both matter | Frequently contested |
| Licence | Suspension, or a driving ban for a foreign licence | Alongside the criminal penalty |
| Vehicle | Confiscation where it belongs to the driver | Not for rental vehicles |
The most productive line of defence is usually technical rather than legal: the interval between driving and testing, the qualification of the facility, the chain of custody of the sample, and whether the analysis distinguishes the active substance from metabolites that persist long after any effect.
Prescribed medication
A number of medicines lawfully prescribed elsewhere contain substances that produce a positive result. Having the prescription is not a complete answer but it changes the case entirely, and it has to be documented — ideally carried with the medication, as noted in the guide on conduct that surprises visitors.
What follows
The criminal penalty is the least of it for most people. The licence measure, the effect on insurance, and — where an accident occurred — the aggravated offences of causing injury or death while driving, dealt with in the guide on road accidents, are what actually bite.
For a foreign licence the position is the same as for alcohol: an Italian court cannot suspend it but can prohibit driving in Italy, and whether that follows you home depends on your own licensing authority. The framework is in the guide on drink driving.
Frequently asked questions
Is a positive test enough to convict me?
That is the central question after the 2024 reform. Substances remain detectable long after any effect, and what the prosecution must prove is being argued in courts across the country.
What happens if I refuse the test?
Refusal is punished as the offence itself, in the same way as refusing a breath test for alcohol.
I have a prescription for the medication.
It is not a complete answer but it changes the case. It should be documented and, ideally, carried with the medication.
Will I lose my licence?
An Italian court cannot suspend a foreign licence but can prohibit you from driving in Italy. Whether that follows you home depends on your own authority.
