Two motocross riders suffered serious leg injuries in a head-on collision on a dirt track near Nelson this afternoon.
The riders were rounding a corner on a popular dirt bike track in the Hira Forest, about 15km east of Nelson, when they collided head-on about 12.30pm.
"It was on a corner so I presume they just didn't see each other until the last minute," Nelson Marlborough Rescue Helicopter pilot Jarrod Colbourne told APNZ.
A 21-year-old men suffered a serious leg injury and was in "quite a bit of pain".
"There were other riders there just helping him out, getting his leg in a comfortable position for him."
