Pamela Anderson walks down a city street and uses her cellphone to book a ride. Along the way, she passes a newspaper and street signs that say, “Hollywood Sexual Harassment Scandal Reaches New Lows” and “U.S. Senator Accused of Groping.” When she gets into the car, she sees another sign that says, “Ride-Hail Drivers Suspected of Rape.” The car doors lock, and the driver turns around and suggestively asks, “Shall we?” Just then, “#MeToo” pops up on her phone’s screen.

“When you accept a ride from a ride-hail app, you also accept the risks that come with it,” Ms. Anderson says in a voice-over. “Many ride-hail companies consider their drivers third-party providers, so they don’t have to accept any responsibility or accountability for their actions. Always ride responsibly.”

The 60-second ad, to be released Monday, is the third in a campaign introduced in 2015 by the National Limousine Association to promote Ride Responsibly, an initiative that encourages riders to “think before you app.”

It is an attempt by the association to focus on allegations of attacks by drivers for ride-hailing companies like Uber and Lyft, which happen to be its competitors. In November, for instance, two women sued Uber, claiming their drivers raped them in separate cases in Florida and California. And last month an Uber driver in Beirut, Lebanon, was arrested in connection with the killing of Rebecca Dykes, a British diplomat.
