According to Ontario Provincial Police, the crash involved one vehicle near Martin Street in Milton.
Police said the vehicle left the westbound Highway 401 and went into a ditch. Emergency responders attended the scene, and four occupants were transported to hospital for medical treatment.

Early-morning highway crashes can involve many factors, including road conditions, visibility, mechanical concerns, driver behaviour or medical emergencies. It would be inappropriate to assume the cause before the investigation is complete.
Two Passengers Reported Seriously Injured
The most serious injuries were reported among two passengers in the vehicle.
The driver and the front-seat passenger sustained minor injuries, according to police. No fatalities were reported in the initial information released about the crash.
Hospitals and emergency services generally do not release personal medical details without consent. Further updates about the condition of those injured may not be made public.
For families and friends of the people involved, the priority remains their recovery and privacy.
Westbound Highway 401 Lanes Reopen
Westbound lanes of Highway 401 near Martin Street were closed while OPP officers investigated the collision and crews worked to clear the area.
The closure affected drivers travelling through Milton during the early-morning period. Highway closures after a serious crash are often necessary to allow paramedics to assist injured people, for officers to document the scene and for debris or damaged vehicles to be removed safely.
Police later confirmed that the affected westbound lanes had reopened.
Motorists travelling through the area should still allow extra time and remain alert for changing traffic conditions, emergency vehicles or residual congestion.
Dangerous-Driving Charge Announced
Ontario Provincial Police said one person has been charged with dangerous driving causing bodily harm in connection with the collision.
A charge is an allegation that must be proven in court. The person charged is presumed innocent unless and until proven guilty.
Police have not publicly released further details about the evidence that led to the charge. Court proceedings may determine what additional information can be released about the allegation, the crash investigation and the events leading up to the collision.
It is important not to identify or speculate about the person charged beyond information officially released by authorities.
Why Crash Investigations Can Take Time
Even when traffic lanes reopen quickly, the investigation into a highway crash can continue.
Officers may inspect the vehicle, photograph the scene, review road conditions, speak with witnesses, examine available video and reconstruct the moments before the collision. In serious-injury cases, investigators may also seek technical assessments and medical information relevant to the incident.
The purpose of the investigation is to establish the facts. Initial reports can change as more evidence becomes available.
For this reason, online posts claiming to know the speed of the vehicle, the condition of the driver or other unconfirmed details should be treated cautiously unless supported by police or court records.
Safe Driving Reminder for Highway 401
Highway 401 is one of Canada’s busiest transportation corridors, and traffic conditions can change quickly, especially overnight and in the early morning.
Drivers can reduce risk by remaining focused, allowing enough following distance, avoiding distractions, wearing seat belts and adjusting speed for weather, visibility and traffic flow.
Anyone approaching a crash scene should slow down, move over when safe to do so and follow directions from police and road crews. Stopping to view or record an incident can create further danger for emergency personnel and other motorists.
