"We believe that the way out of the crisis is essentially political. This decision excludes any use of violence that only adds chaos to adversity," Le Pen said in a letter published on the party's website.
She noted that the political solution to the crisis depended on the authorities, stressing that French President Emmanuel Macron "is deprived of sympathy for the people, constrained by arrogance and indifference of the elites."
The so-called yellow vest protests, named after the reflective vests all French drivers are required to keep in their cars, have been ongoing in France since November 17 in response to the government's plans to raise fuel tax.
At least four people have died in the protests that turned violent and hundreds have been injured.
