The driver of the bus that crashed in Co Meath killing five schoolgirls was never told his bus was fitted with an Anti-locking Brake System.
John Hubble was giving evidence at the Circuit Criminal Court on the second day of the trial of two companies in relation to the Navan bus crash.
Today is the third anniversary of the crash, in which five teenage girls were killed.
58-year-old John Hubble told the court he had been driving for decades, had a clean driving licence and was doing his regular school-run on the day of the accident.
He said he had never been informed the bus he drove was fitted with ABS.
He said he had never been given instruction on the system.
When gardaí showed Mr Hubble that a bulb indicating the ABS was not working and was removed from the driving panel, he was 'shocked'.
The proseuction allege both defendants were aware the ABS was not working on the bus and that the warning light was also broken.
Mr Hubble gave evidence that before the bus crashed he braked and the bus 'quivered' to the right hand side of the road.
When he braked for a second time the tail of the bus swung right around, causing the bus to topple and crash into the ditch.
McArdles Test Centre issued the bus with a certificate of roadworthiness two months before the crash.
Mr Hubble said he had had no problem with the brakes but whenever he had a problem he said he would bring the bus 'straight to Keltank' to get it fixed.
Counsel for Keltank Ltd, Roderick O'Hanlon, put it to Mr Hubble that as he was not aware of the ABS - he likewise did not know that Keltank never serviced, maintained or repaired ABS systems on buses. Mr Hubble agreed.
Keltank Ltd, and McArdles Test Centre are charged with offences connected to the maintainence of the bus. Both are pleading not guilty.
The case continues on Monday.
