Capt. Greg Bacher said in a release that officers expect to issue at least 10 citations for traveling too fast for conditions.
"It's sometimes impossible to keep the highways completely ice and slush free, so drivers should expect the unexpected," Bacher said.
The Pennsylvania Turnpike Commission also announced it has begun a full review of the Feb. 14 accidents, which occurred about seven miles east of the Willow Grove interchange in Bucks County.
The turnpike said its review would take several weeks to complete. A legislative hearing on the matter and other weather-related vehicle crashes also is being planned.
Investigators are assembling a timeline and collecting information about communications, response times and other factors from emergency responders, turnpike employees, victims and witnesses.
"We absolutely want to understand if there was something we could have done that may have prevented or somehow mitigated the crashes," said turnpike chief executive Mark Compton. "Plus, we need to consider if there's something different we could be doing ... in the future."
Officials said Friday most of the injuries were minor.
