The Paris region and the entire Île-de-France are experiencing exceptionally heavy traffic conditions at the start of this week. On Monday, January 5th, the area recorded over 1,000 kilometers of traffic jams, while RATP services faced significant disruptions on RER lines, with a complete suspension of bus operations. The severe overnight frosts turned roads into icy skating rinks, making travel hazardous for all commuters.
Météo-France has issued an orange alert for snow and ice covering 26 departments in the greater northwest region through Tuesday morning. The weather agency emphasized the risk of "severe freezing," leading to very slippery conditions on the roads at dawn. In Normandy, reported snowfall by 4 p.m. Monday ranged from 2 to 7 centimeters, with local peaks of 10 to 15 centimeters in higher elevations. If you plan to travel on Tuesday, it's advisable to allow extra time and check traffic conditions before heading out.
The Police Prefect and Prefect of the Paris Defense and Security Zone has implemented strict measures to reduce the risk of accidents. From Monday, January 5 at 2 p.m. until Tuesday, January 6 at 10 a.m., heavy goods vehicles over 3.5 tons are completely banned from the road network within the territorial perimeter of the PNVIF. This ban also applies to vehicles transporting hazardous materials.
Speed limits are set to 80 km/h for all vehicles across all routes within the Île-de-France road network during this period. Vehicles designed for passenger transport, including buses, coaches, and school vehicles, are not allowed to overtake. These measures aim to ease traffic flow and minimize accident risks on roads made hazardous by ice. The prefectural decree 2026-010 provides comprehensive details of these regulations.

For those forced to hit the roads, it's essential to double-check your vehicle's condition, especially your tires. Given the current snow and icy conditions, it's advisable to equip your vehicle properly and carry the right gear to stay safe.
For drivers, safety precautions should start even before turning the key in the ignition. It's essential to thoroughly clear snow and ice from your vehicle before hitting the road: windshield, windows, headlights, and license plates. Beware—leaving a mirror or roof covered in snow could prove costly, as it can result in a fine of 68 euros.
The Road Safety Authority is reminding drivers of essential safety tips for traveling in snowy and icy conditions. In short, if you want to make it to work on time this morning, it’s best to leave very early or consider working from home if your employer allows it.
Weather forecasts indicate that conditions are gradually improving throughout the morning. The lifting of traffic restrictions is scheduled for 10 a.m. on Tuesday, January 6, 2026, but caution remains advised as temperatures remain below freezing. The Paris Police Prefecture recommends checking the latest Météo-France updates and traffic alerts before heading out. Stay informed with official updates and track real-time developments on the Île-de-France Mobilités website.
