**A40 Collision Leaves Two Hospitalised as Driver Arrested on Suspicion of Drug Driving**

A major incident on a busy stretch of the A40 near Llandeilo disrupted traffic for several hours on Tuesday morning, after a serious collision led to two people being transported to hospital and one individual taken into police custody. Emergency services, including Dyfed-Powys Police and the Welsh Ambulance Service, responded to the scene shortly after reports came in at around 8:15am.


The crash, involving a white Lexon van and a grey Volkswagen, prompted the closure of both carriageways of the A40, a significant route connecting communities in Carmarthenshire. The incident occurred near Manordeilo Service Station, an area known for its steady flow of vehicles during the morning rush hour. Authorities quickly established diversions while emergency responders worked to assist casualties and clear the scene.
A spokesperson for Dyfed-Powys Police confirmed that the injured parties were taken to hospital by ambulance, though details regarding their condition were not immediately disclosed. The impact of the collision was such that the road remained inaccessible for nearly three hours, reopening only at approximately 10:35am as clean-up operations were completed.
Attention has centred on a 29-year-old man who was arrested at the scene on suspicion of driving whilst under the influence of drugs. He was subsequently taken into police custody, where inquiries continue. The police have emphasised the seriousness with which these allegations are being treated, citing the need for public safety on Welsh roads.
Investigators are now appealing for witnesses who may have seen the events leading up to the incident, or who have relevant dashcam footage, to come forward. Dyfed-Powys Police have provided several ways for the public to share information, encouraging anyone with details to make contact either online, by email, or by phone. The investigation continues to examine all factors that may have contributed to the collision.
This event highlights ongoing concerns about impaired driving and its dangers to the public. The region has seen a number of high-profile campaigns in recent years reminding motorists of the consequences of getting behind the wheel under the influence of drugs or alcohol. Road safety advocates maintain that continued vigilance is necessary to prevent future tragedies.
The disruption to a major route such as the A40 has also brought into focus the impact that serious accidents have on the wider community. Commuters, local residents, and businesses were all affected by the extended closure of the road, underlining the far-reaching consequences of such incidents beyond those directly involved.
As authorities work to piece together exactly what happened on Tuesday morning, there is a renewed call for responsible driving and for anyone with potentially useful information to assist the police. Updates regarding the condition of those hospitalised and any formal charges against the individual in custody are expected as the investigation progresses.
