Waikato police are urging motorists to slow down after attending 10 crashes overnight.
District road policing manager, Inspector Freda Grace said two of the biggest crashes, between 4.30pm yesterday and 7.30am today, involved trucks.
"Just before 6am emergency services were called to a crash on SH39/Ormsby Rd at Puketotara, between Pirongia and Otorohanga, where a southbound LPG tanker has left the road and come to rest in ditch.
"The truck ended up facing north part way in the southbound lane, there were no injuries suffered in the crash and there has been no fuel leak and the road is open but may have to be closed for a few hours to recover the tanker."
On the other side of the district emergency services were currently working to recover a truck and trailer unit that crashed, closing SH25 between Waihi and Whangamata about 6.30am.
