The decision on whether to charge a coach driver arrested on suspicion of drink driving after a crash on the M1 has been put back to 2008.
The coach hit the kerb, a tree and lamppost before overturning
The National Express coach crashed at Newport Pagnell service station in Buckinghamshire in September.
The driver, 35, from West Bromwich has been bailed until 28 January.
Police say delays in receiving forensic evidence mean the Crown Prosecution Service cannot make a fully-informed decision on whether to bring charges.
The coach was travelling from Birmingham to Stansted Airport in Essex when it overturned at Newport Pagnell services on 3 September.
Police have not released the name of the driver who was injured in the crash along with five passengers.
