Police have announced where they expect the biggest crowds.

The Croatian police have issued warnings about heavy traffic congestion during the extended weekend, particularly on roads leading towards the coast. According to the Ministry of Internal Affairs, increased traffic is anticipated due to the arrival of foreign tourists, the start of summer holidays, and higher vehicle transit. The most significant bottlenecks are expected along the A1 motorway near toll stations such as Lučko and Demerje, between Lučko and Bosiljevo, on the Istrian Ypsilon route, at exits from the A2 motorway near Trakošćani, on the Zagreb bypass, at entrances to tourist centers, ferry terminals, border crossings, and airports.

Authorities have emphasized that increased traffic often leads to a rise in road accidents, primarily caused by serious violations of traffic regulations. To address this, the police will conduct intensified preventive and punitive measures on main routes heading toward coastal areas and tourist destinations over the weekend. Maximum numbers of officers will be deployed, utilizing all available traffic monitoring equipment, including speed radar devices, breathalyzers, and drug testing kits. Special attention will be given to four major causes of severe accidents: driving under the influence of alcohol, speeding, failure to use seat belts, and using mobile phones while driving. Motorcyclists will also face heightened scrutiny.

In some locations, police will manually regulate traffic flow. The Ministry of Internal Affairs has stated that officers will physically manage traffic at the most congested points to reduce delays and improve the movement of vehicles. Traffic control will also be conducted from the air, with police helicopters being used when necessary.

Before embarking on their journeys, drivers are advised to check the technical condition of their vehicles, obtain information about road conditions and weather forecasts, and ensure they are well-rested before setting off. They are encouraged to avoid traveling during peak times—Friday afternoons, Saturday mornings, and Sunday afternoons. Drivers are reminded not to drive under the influence of alcohol, to use seat belts, adjust their speed according to road conditions, maintain sufficient distance between vehicles, and avoid risky overtaking maneuvers.

Authorities have called upon all road users to respect traffic rules, exercise patience, and show mutual tolerance to minimize traffic accidents and casualties during the weekend.

During the heightened traffic surveillance over the weekend, the Zagreb police recorded over 365 traffic violations in one night. One in seven drivers tested positive for alcohol consumption, and 40 percent of the violations were related to excessive speed. The action was part of a preventive and punitive effort aimed at addressing the negative trends in road safety, focusing mainly on drunk driving and drug use but also targeting other serious traffic offenses that endanger road safety.

Out of the total 365 violations, 142 were for exceeding the speed limit, accounting for nearly 40 percent. Fifty drivers were found to be under the influence of alcohol, and thirty-eight did not wear seat belts. Nineteen drivers were sanctioned for using mobile phones while driving.

These figures come following a serious traffic accident at the intersection of Zagreb Avenue, Savska Street, and Slavonian Avenue where a 33-year-old motorcyclist died on Saturday. The accident occurred when a motorcycle collided with a private car attempting to turn from Slavonian Avenue into Savska Street, which is now prohibited due to new traffic regulations resulting from the removal of the Vjesnik skyscraper. Several individuals were seriously injured in the crash.

The police noted that the deceased motorcyclist had not obtained the required A category license for the type of motorcycle he was riding, although based on the vehicle's technical specifications, the A category license was not actually required.

Authorities once again urge drivers to abide by traffic regulations and warn that inappropriate speed, alcohol, and carelessness remain among the most common causes of the most severe traffic accidents. The statistics recorded during just one night of monitoring indicate that despite frequent warnings and police actions, many drivers continue to knowingly violate traffic rules, putting themselves and others at risk.
