Bus Malfunction Spews Thick Smoke on Andorra's CG1 and CG2 Roads

A national bus bound for Encamp emitted heavy smoke from faulty combustion on Andorra's CG1 and CG2 near Obac, alarming drivers with poor visibility but causing no accidents or major disruptions.

Key Points

  • Thick smoke plume appeared after 9am near KM0 roundabout on CG1 and CG2
  • National line bus to Encamp caused smoke due to poor fuel combustion
  • Visibility severely reduced for vehicles behind the bus
  • No fire or accidents reported; bus continued to operate

Drivers on Andorra's CG1 and CG2 roads experienced alarm shortly after 9am when a thick plume of smoke appeared, initially raising fears of a fire or serious incident.

The smoke, visible especially around the KM0 roundabout and stretching slightly further along the route, caught motorists off guard as it grew denser. Those approaching or following closely struggled with severely reduced visibility.

The cause soon became clear: a regular national line bus heading towards Encamp suffered from poor combustion in its fuel system, producing the heavy smoke trail. The emission was so intense that it obscured the view for vehicles directly behind it.

Once identified, the situation eased concerns among road users, confirming no major hazard like a fire. The bus continued operating despite the fault, though operators will need to address the mechanical issue.

The episode unfolded on the Obac road section, affecting traffic on both CG1 initially and then CG2, but caused no reported accidents or disruptions beyond the momentary uncertainty.
