Largescale strikes by UK workers last month have led to experts warning of increased traffic on our roads. Drivers are competing for tarmac as traffic in and around cities becomes much higher than normal leading to more jams on all major roads. INRIX, part of the motor trade industry, study traffic analytics and saw travel times increase by 14% compared to the same period last year, with stretches of the M25, M60, M6 and M40 unfortunately seeing some of the longest traffic jams.
