The GNR chased a truck on the A22 on Friday night, all the way from the Tavira junction to the Guadiana bridge.
Several other drivers on the A22 had alerted emergency services to the irregular driving of a heavy vehicle weaving "between the left and right lanes" of the A22.
The GNR pursued the truck driver from the Tavira junction, all the way to the Guadiana bridge, alerting the Spanish Guardia Civil of the situation.
The Guardia Civil in Spain eventually managed to intercept the vehicle on the A-49, in the Huelva area, and the driver was detained.
