A Tenerife youth may be the first to be jailed under the new tougher traffic laws.

The 22-year-old was caught by a radar trap on a Santa Cruz dual carriageway, driving his VW Golf at 170 km/h, more than 90 km/h above the speed limit.

He was tracked on traffic cameras and arrested minutes afterwards as he parked his car near the Auditorium. Under the new law, speeds in excess of 60km/h in built-up areas and 70 km/h on main roads, including motorways, automatically entail a 3-6 month prison sentence for the offender.
