The remand order was issued by magistrates court assistant registrar Puteri Nordina Kamalaudin following an application by police.

Earlier, Perak police chief Mior Faridalathrash Wahid said the 34-year-old driver had on record 13 traffic offences between 2008 and last year, three of which were related to road accidents.

“However, the urine test showed that the man was not driving under the influence of drugs,” he said in a statement.

He said the case was being investigated under Section 41(1) of the Road Transport Act 1987 for causing death by reckless or dangerous driving.

Mior Faridalathrash said the investigation into the accident revealed that the unloaded trailer, which was heading towards Bukit Beruntung, Selangor, from Taiping, Perak, had crashed into the rear of a car with four family members in it.

“The impact caused the trailer and car to plough into five other vehicles. The other vehicles were badly damaged but all drivers and passengers escaped unhurt,” he added.

Mior Faridalathrash urged those who witnessed the accident to contact the investigating officer, Tarmini Che Hassan, at 013-594-9441 to assist in the investigation.

The horrific accident killed retired policeman Rahim Ramli, 60, his wife Siti Petimah Omar, 59, and their two daughters, Nor Hadirah, 28, and Nor Hamizah, 27.
