Italy is preparing a significant change to its motorway traffic regulations that could see drivers fined up to €160 for travelling too slowly in the overtaking lane. The proposed legislation introduces a minimum speed requirement of 100 km/h in the far-left lane of motorways with at least three lanes in each direction, although several important exceptions will apply.
The measure is part of a broader effort by the Italian government to improve motorway traffic flow, reduce unnecessary congestion and discourage drivers from occupying the overtaking lane without sufficient reason.
Italy Proposes a 100 km/h Minimum Speed in the Left Lane
Under Article 50 of the proposed legislation, motorists driving below 100 km/h in the far-left lane of qualifying Italian motorways could face fines of up to €160.
However, the proposed restriction will not apply to every motorway in Italy. It will specifically cover motorway sections featuring at least three traffic lanes in each direction, where the leftmost lane is primarily intended for overtaking.
The proposal was approved by Italy’s Council of Ministers in mid-October and has subsequently entered the parliamentary process. Its final adoption is still pending, meaning the new minimum speed requirement is not yet an enforceable nationwide rule.
Although Italy currently has no specific statutory minimum speed for the overtaking lane, existing traffic regulations already require motorists to use motorway lanes correctly and avoid unnecessarily occupying the left lane.
Driving Slowly in the Overtaking Lane Is Already Prohibited
The proposed amendment builds on two important provisions of Italy’s existing Highway Code.
Article 141 requires drivers to adapt their speed to road conditions, traffic density, visibility and other circumstances affecting driving safety. Meanwhile, Article 143 establishes the principle of keeping to the right-hand lane whenever it is available, using the left lanes primarily for overtaking.
In practical terms, drivers should return to the right-hand lane after completing an overtaking manoeuvre rather than continuing to cruise in the far-left lane.
The proposed 100 km/h threshold would introduce a more specific requirement for certain multilane motorways, giving authorities an additional basis for penalising drivers who unnecessarily obstruct faster-moving traffic.
Exceptions for Bad Weather, Accidents and Roadworks
Importantly, the proposed legislation does not mean motorists will be forced to maintain a speed of at least 100 km/h regardless of driving conditions.
Exceptions will apply whenever road or traffic conditions make such speeds unsafe or inappropriate. These include heavy rain, dense fog, reduced visibility, traffic accidents and roadworks.
In these circumstances, drivers will be expected to adjust their speed according to the actual conditions, even if that means travelling below the proposed 100 km/h minimum.
This distinction is particularly important because road safety remains the priority. A minimum speed requirement should never encourage motorists to drive faster than conditions safely allow.
When Will the New Italian Traffic Rules Come Into Force?
Despite approval by the Council of Ministers, the proposed amendment has not yet completed the parliamentary process. Its final wording, implementation details and effective date will depend on the outcome of the legislative debate.
Until Parliament formally adopts the changes and the relevant provisions enter into force, drivers should continue following Italy’s existing Highway Code.
For international motorists, including tourists travelling through Italy on their way to other European destinations, the proposed regulation is worth monitoring. If adopted, it could introduce an additional traffic rule to consider when using Italy’s major three-lane motorways.
Ultimately, the government’s objective is straightforward: keep the overtaking lane moving, discourage unnecessary slow driving and make motorway traffic more predictable. However, whether a fixed 100 km/h threshold will deliver those benefits without creating new challenges for drivers remains to be seen.
