Imported vehicles are piling up at European ports, turning them into “car parks” as automakers and distributors struggle with a slowdown in sales and logistical bottlenecks including the lack of truck drivers.

Port and car industry executives have pointed to a pile-up of Chinese electric cars as one of the leading causes of the problem, with some companies booking shipping delivery slots without ordering onward transportation. In other instances, carmakers in general are struggling to order trucks because of the lack of drivers and equipment to move the vehicles on.

“Car distributors are increasingly using the port’s car parks as a depot. Instead of stocking the cars at the dealers, they are collected at the car terminal,” said the Port of Antwerp-Bruges, whose port at Zeebrugge is Europe’s busiest port for car imports. “All major car ports” were struggling with congestion, the port added, without specifying the origin of the vehicles.
