The incident, which occurred around 7:30 AM at kilometer 5.200 of the A-6 heading towards the capital, resulted in a traffic jam of approximately three kilometers. The breakdown, not cleared until 9:00 AM, created serious mobility issues coinciding with rush hour and the mass movement of students to their exams.

In response, the Complutense University of Madrid implemented exceptional measures. Access to classrooms was permitted until 10:00 AM for students affected by the traffic, ensuring no one would be penalized. Those arriving within this window could complete their 90-minute exam until 11:30 AM, without exceeding the established time limit, except for certified accommodations.

The university also stipulated that no student could leave the exam hall before 10:15 AM at the examination centers within the Community of Madrid, to maintain the integrity of the test. For those unable to access the venue before 10:00 AM, the option to take the exam on June 5th as an incident was offered.

The PAU is currently being held at the six public universities in Madrid, with over 42,000 students participating. The incident on the A-6 particularly impacted candidates heading to the Ciudad Universitaria campus, one of the region's main examination sites.
