Traffic is very slow and building on the M62 after an accident which closed two lanes just before junction 26.
Highways England Yorkshire tweeted that motorists should allow extra time for their journey.
They added: "Traffic delays currently building."
The accident happened between M62 eastbound between J25 (Brighouse) and J26 (M606).
A motorist who passed the scene said three vehicles were involved - but it did not appear serious.
She said traffic was already "very slow."
