Three of the men, including the driver were killed, while the other four were taken to hospital with serious injuries, police said.

Police said it was raining heavily at the time and believe the minivan lost traction as the driver applied the brakes.

tractionは「静止摩擦」なので，loseと併せると「コントロールが効かなくなる」となります。おそらくはハイドロプレーニング現象（米 hydroplaning，英aquaplaning）が起こったのでしょう。

昨日は中央道と４号線で都内へ入りましたが，視界が効かないほどの雨量の中，路面の悪いところにたまった水でこれを何度か経験しました（大雪だったので今年はとくに路面がひどいと感じています）。 traction controlや4WDが付いているクルマだったらちょっとは違ったかもしれません。梅雨時の運転は細心の注意が必要です。（UG）
