“Need a lift?” (also: “Need a ride?)
— “Mau nebeng/numpang gak?”
When you say “(Do you) need a lift?” to someone, it means you’re offering someone a ride in a car with you. “Give someone a lift” means to provide transportation for someone e.g. take someone somewhere in your car (also “give someone a ride”).
• I’ve got to go to the train station. Can you give me a lift?
• Can you give me a lift to work tomorrow? My car is being repaired.
• It’s too late to walk home. Need a lift?
